Abstract

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 Mn doped 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.
