Optical Exploration on Eu3+ Ions Doped Borophospho-Silicate Glasses for Red Luminescent Applications Raja Prince Selvaraj, Gopalan Muralidharan, Kammalamuriyil Ahammed Basheer Naseer, Ranjib Kumar Padhi, Kethappan Marimuthu International Journal of Applied Glass Science, 2026 Eu 3+ ions embedded in borophospho‐silicate glasses were synthesized using the melt‐quenching technique to explore their optical and spectroscopic properties. The calculated bonding measurements explored through their absorption spectra reveals a covalent character. Luminescence behavior has been examined via excitation and emission profiles, revealing prominent emissions in the red spectral region. A phonon sideband on the higher energy side of the 7 F 0 → 5 D 2 transition indicates electron‐phonon coupling, revealing the phonon energy (ђω). Addition of modifier cations affected luminescence intensity by influencing the ligands around the Eu 3+ ions that altered JO parameters and radiative traits; where as a high Ω 2 value implied strong covalency and asymmetry. Stimulated emission cross‐sections () and branching ratios (β R ) confirmed their suitability for red luminescent applications. Chromaticity coordinates positioned its emission in the red range, supporting their potential for Red‐LED devices. The luminescence decay patterns of the fabricated glasses displayed a triple‐exponential profile across all samples. The experimental decay lifetime was obtained via curve fitting of the luminescence decay and subsequently compared with the theoretically calculated values. The attained results specify that BPSE:Na and BPSE:Ba glasses are promising candidates for optoelectronic and laser‐based technologies.
Comprehensive investigations on physical, structural, optical, and radiation attenuation properties of bismuth-incorporated boro-tellurite glasses D. Keerthana, K.A. Naseer, S. Arul Raja Sekaran, M.I. Sayyed, Mohammed S. Alqahtani, K. Marimuthu Radiation Physics and Chemistry, 2026 In the present investigation, a new series of Dy 3+ doped Bismuth - incorporated boro-tellurite glasses were fabricated employing the standard melt-quenching technique with the nominal composition of (59− x )B 2 O 3 +20TeO 2 +10ZnF+10BaO + x Bi 2 O 3 +1Dy 2 O 3 ( x = 0, 5, 10, 15, and 20 in wt%). And a variety of analytical tests including XRD , FTIR , and UV–Vis–NIR spectroscopy, were conducted. The outcome of these analytical tests was used in exploring the suitability of the prepared glasses for radiation shielding purposes. Here, XRD analysis is utilized to analyze the amorphous character of the fabricated sample for phase identification. Additionally, the produced glass was subjected to FTIR analysis ; the presence of functional groups and their matching band assignments in the glass samples were explored. For the fabricated glasses, contemplation is given to their physical and structural characteristics as well as their elastic qualities. The optical characteristics, such as the energy transitions associated with the trivalent Dy 3+ ions, Urbach energy, and direct &indirect bandgap energy using Tauc plot tactic are made clear by the UV–Visible–NIR absorption spectra . The Phy-X/PSD software program was used for the simulations to assess the radiation shielding potential of the prepared material. • Dy 3+ ions doped Bismuth incorporated Boro-tellurite were fabricated via melt-quenching technique. • The structural properties prove that the glasses are closely packed. • The elastic properties are varying with the modifier. • Phy-X/PSD simulation software is used to analyze the shielding performance. • ZBaT20Bi is the best glass material among the investigated glass sample.
