Study of structural, morphological and optical properties of Mn+2 doped CdS nanoparticles synthesized at various doping concentration Rajiv Ranjan, C. M. S. Negi, Shiv Kumar Choubey, K. P. Tiwary Chalcogenide Letters, 2023 Manganese-doped cadmium sulphide semiconductor nanoparticles (CdS: Mn) NPs have been created utilizing a microwave-assisted solvothermal technique at different Mn concentrations (0, 1%, 3%, and 5%). The chemicals utilized for the preparation of Mndoped CdS nanoparticles were sodium sulphide (Na2S.xH2O), manganese chloride (MnCl2.4H2O), and cadmium acetate (CH3COO)2Cd., H2O). To determine the structural dimensions of the generated nanoparticles, the Debye-Scherer equation was used to calculate the average crystallite size at the full-width half maximum (FWHM) of the diffraction peaks. FTIR spectra analysis was used to look at the various functional and vibrational groups present in the Mn-doped CdS nanoparticle sample. The structure features of the produced nanoparticles have been examined using X-ray diffraction patterns. Energy dispersive X-rays were employed to ascertain the chemical composition of the synthesized nanoparticles. The optical properties and quantification of the energy band gap of the nanoparticles have been done using UV-V spectroscopy. According to XRD calculations, the cubic zinc-blend structure of the generated NPs had a crystal size of between 4 and 7 nm. By using EDX spectroscopy, the incorporation of Mn at the CdS lattice was confirmed.
INFLUENCE OF NICKEL ON STRUCTURAL AND OPTICAL BEHAVIOUR OF CADMIUM SULPHIDE NANOPARTICLES K. P. TIWARY, , F. ALI, R. K. MISHRA, S. K. CHOUBEY, K. SHARMA, , , , and Journal of Ovonic Research, 2020 Cadmium Sulphide being an important II-VI compound semiconductor has wide applications in various optoelectronic and biolabeling devices. In the present work, undoped and Ni (2%, 4%, 6% and 8%) doped CdS nanoparticles were synthesized in aqueous medium by microwave assisted solvo thermal method using cadmium acetate, nickel chloride and sodium sulphide as precursors. The effect of Ni doping on the Structural, Morphological and Optical Properties of CdS nanoparticles have been studied by X- ray diffraction, SEM, FTIR, PL and UV-Visible spectroscopy. The crystal structure and morphology of the as synthesized nanoparticles have been investigated by X- ray diffraction and scanning electron microscopy (SEM). The XRD results revealed the crystalline nature of the nanoparticles. The average grain size of the nanoparticles was estimated using Scherrer equation which was found to be in the range of 4.2 - 6 nm. The FTIR spectra were also recorded to identify the presence of various functional groups in the synthesized CdS nanoparticles. For the estimation of the optical energy band gap of as synthesized nanoparticles, absorption spectra were recorded using UV- Visible spectrophotometer. The result of UV-Visible spectra revealed the increment of energy band gap in CdS nanoparticles on increasing the concentration of Ni.
