Scientific Reports, 2026
A series of glass samples with the nominal composition 65SiO 2 - (22.5-x) Li 2 O − 12.5Al 2 O 3 - xTiO 2 , where x varies as 2.5, 5, 7.5, and 10 mol%, were synthesized using the conventional melt-quenching technique. Differential scanning calorimetry (DSC) was utilized to identify crucial thermal transitions, which informed the process of fabricating corresponding glass-ceramic derivatives. X-ray diffraction (XRD) analysis confirmed the formation of three primary crystalline phases in the glass-ceramics: lithium disilicate (Li₂Si 2 O 5 ), lithium aluminosilicate (LiAlSiO 4 ), and brookite (TiO 2 ). Scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDAX) demonstrated that crystal growth increased in size and developed well-defined morphologies. Vickers microhardness testing indicated that TiO 2 -doped lithium silicate glasses and their glass-ceramic counterparts exhibit mechanical properties compatible with dental application requirements. Differential scanning calorimetry (DSC) analysis revealed that increasing TiO 2 content (2.5–10 mol%) shifted thermal transitions to higher temperatures, indicating improved thermal stability and a stronger glass network. Higher TiO 2 also enhanced microhardness (5.02–5.93 GPa) and compressive strength (440–542 MPa), with further gains after heat treatment due to TiO 2 -induced crystallization of hard phases. Corresponding glass-ceramics showed increased hardness (5.51–7.27 GPa), compressive strength (492–583 MPa), and density (2.478–3.441 g/cm³), confirming the reinforcing and densifying effects of TiO 2 . Fourier transform infrared spectroscopy (FTIR) results suggested that modifiers such as Li 2 O and TiO 2 disrupt the SiO 4 tetrahedral network by introducing non-bridging oxygens (NBOs) and weakening some bonds, thereby affecting network polymerization and structural rigidity. TiO₂ incorporation enhanced thermal stability, hardness, and compressive strength, with further gains after heat treatment due to TiO 2 -induced crystallization. FTIR analysis confirmed structural modifications promoting a stronger glass network. These improvements yield glass-ceramics with mechanical and thermal properties comparable to dental enamel, enhancing their suitability for restorative applications.
Investigation of the phosphorescence, persistent decay and structure properties of Eu2+: strontium aluminate doped with Nd3+, B3+ or Dy3+

BMC Chemistry, 2025
Luminescent sources based on crystalline materials doped with transition metal or rare-earth cations are known as persistent phosphors, and they can continue to emit light even after the excitation source has disappeared. The present study aims to prepare strontium aluminate with varying weight percentages of Eu 2+ , RE 3+ (RE = Dy 3+ , Nd 3+ , or B 3+ ) oxides by the solid-state preparation followed by firing under active carbon at 1250 °C.The produced phosphors were examined using FTIR spectroscopy, mechano-luminescent measurement, scanning electron microscopy (SEM), and X-ray diffraction (XRD). A bulk density and apparent porosity measurement was also used to assess the impact of the firing temperature at 1250 °C. Photoluminescence characteristics were examined concerning the kind of trivalent oxides doped in strontium aluminate. The results showed that for samples containing 0.15 weight% of Eu 2 O 3 and 0.15 weight% of RE 2 O 3 , SrAl 2 O 4 formed with Eu + 2 , RE 3+ as a single phase. However, RESr 2 AlO 5 was formed together with a minor amount of SrAl 2 O 4 when the Eu 2 O 3 contents decreased at the expense of the RE 2 O 3 contents. Additionally, it was observed that the Eu 3+ was converted into Eu 2+ for every sample. Every sample had porous behavior, and the bulk density was increased by the inclusion of RESr 2 AlO 5 in addition to SrAl 2 O 4 . Transitions from the 4f 6 and 5d 1 configurations of the emission center (Eu 2+ ions) to the 4f 7 configuration result in a broad band at peaks of 517 nm in the emission spectra of all the samples. Samples containing RESr 2 AlO 5 exhibit high phosphor color characteristics, forming red-orange phosphors encircled by green phosphor rings. Compared to samples containing Nd 2 O 3 and B 2 O 3 , those containing Dy 2 O 3 phosphor have the highest decay time values.

Glasses based on the basic composition of lithium disilicate (Li2O.2SiO2) together with derived samples containing increasing CeO2 replacing Li2O (0.1, 0.2, 0.5, 1 Mol %) were prepared by melting – annealing method, samples from the prepared parent glasses were thermally heat treated through two-step regime (450° C /10 h – followed by 650° C / 6 h) to convert them to their glass – ceramics derivatives. The main purpose of this study is to find out the main properties of the prepared glass – ceramics to be applied as dental candidates. The optical, FTIR, and thermal expansion properties of the parent glasses were examined to identify the main structural groups which are defined as tetrahedral stronger SiO2 building groups. The detailed separated crystalline phases within the prepared glass–ceramics were identified together with their textural features. The Vickers microhardness data for both the parent glasses and their glass -ceramics derivatives were evaluated. SEM and EDAX measurements indicate the ability of the prepared samples to form hydroxyapatite upon immersion in SBF solution.

Applied Physics A Materials Science and Processing, 2023
Undoped glass of chemical composition 70B2O3–25NaF–5La2O3together with Nd2O3-doped samples were prepared via conventional melt and annealing procedure. The prepared glasses were investigated through photoluminescence measurements to find out their extent for the lasing application. The undoped sample reveals two UV absorption peaks while Nd2O3-doped samples show 10 well-characterized peaks in the UV–Visible range that are correlated to different transition states of Nd3+ions. Three different bands are detected in the emission spectra at 875 nm (4F3/2 → 4I9/2), 1056 nm (4F3/2 → 4I11/2), and 1326 nm (4F3/2 → 4I13/2). The Judd–Ofelt parameters (Ω2, Ω4, Ω6) and radiative properties were estimated using the Judd–Ofelt theory. The represented data indicated that the transition line4F3/2 → 4I11/2is the sharpest and lowest bandwidth value than other detected transitions. The structural analysis by FTIR vibrational modes suggested that the IR absorption bands within the range 800–1200 cm−1originate from both combined vibrations of tetrahedral (BO4) and (BO3F) groups together with (NaF4) groups beside triangular BO3groups which are vibrating within the range 1200–1600 cm−1. The addition of Nd2O3is assumed to cause the possible transformation of some structural B–O bonds within the range of triangular borate units referring to the possible formation of pyroborate units or similar structural groups.
Effect of CuO doping on structural features, optical absorption and photoluminescence behavior of ZnO-based glasses

Journal of Materials Science Materials in Electronics, 2023
Glasses composed of ZnO–SiO2–B2O3–In2O3 with the addition of different content of CuO were prepared by a popular melt–quenching methodology. The effect of the addition of copper oxide in the glass network was investigated using density, FTIR spectroscopy, optical absorption, and photoluminescence spectroscopy. By increasing the concentration of CuO, a decrease in the density is observed, indicating structural changes in the glass network. The structural building units of glasses are $${\\mathrm{BO}}_{3}$$ BO 3 ,$${\\mathrm{BO}}_{4}$$ BO 4 , and $${\\mathrm{ZnO}}_{4}$$ ZnO 4 according to the FTIR spectra. The absorption spectra of these glasses reveal a distinct broad band at 744 nm due to 2$${\\mathrm{B}}_{1\\mathrm{g}}$$ B 1 g → 2$${\\mathrm{B}}_{2\\mathrm{g}}$$ B 2 g characteristic transition of cupric ion in the distorted octahedral sites. The optical band gap energies ($${E}_{\\mathrm{g}}$$ E g ) and refractive indices of the studied glasses were also evaluated using the ASF, DASF, and Tauc techniques which revealed that (Eg) values are in gradual decrease with a rise content of CuO. The photoluminescence analysis including emission and CIE chromaticity of the prepared samples were carried out. The emission spectra supported divalent state of copper ions in a distorted octahedral geometry of the glass network upon UV excitation at 270 nm. These results may suggest the material of glass as a potential candidate in the photonics applications.
Behavior of bismuth ions in the two glassy systems of 50 LiF-50 P2O5 and 50 LiF-50 B2O3 (mol %) assessed by optical, FTIR and photoluminescence spectra in addition to thermal expansion properties

Optical and Quantum Electronics, 2023
Glasses from two varieties of (LiF-B2O3) and (LiF-P2O5) systems with equal 50 mol % for each partner together with samples doped with 1 or 2% Bi2O3 were synthesized by melting–annealing mechanism. Multiple optical, FTIR and photoluminescence spectral measurements were carried out. Optical spectra of Bi2O3—doped glasses exhibit UV-near visible peaks owing to the specific absorption of Bi3+ ions. FTIR spectra elucidate the presence of characteristic vibrational bands from (LiF-B2O3) glass due to (BO3) and (BO3F) groups beside (LiF4) groups while the fluorophosphate glasses (LiF-P2O5) show vibrations due to PO4 and (PO3F) groups and also the possible sharing of (LiF4) groups. Photoluminescence spectral data reveal extended emission from about 375 to 700 nm and is more prominent in (LiF-B2O3) system than (LiF-P2O5) system. The thermal expansion data reveal similar behavior and the derived transition and softening temperatures are slightly lower in (LiF-P2O5) glasses than (LiF-B2O3) glasses.
