CdS being a wide band gap II-VI semiconducting material with better lattice matching properties is made suitable option for solar cell applications. In the present work, CdS nanoparticles were prepared by chemical precipitation technique in the presence of organic solvent. Cadmium sulphate [3CdSO4 .8H2O] and thiourea [(NH2)2CS] were used as precursor materials and N, N- Dimethylformamide (DMF) was used as an organic solvent. NaOH solution is used for maintaining pH 8 and 12. The obtained CdS nano particles were characterized by X-Ray Diffraction (XRD), Particle Size Analyser (PSA), Scanning Electron Microscope (SEM), Energy Dispersive X-ray spectrometry (EDX), Transmission Electron Microscope (TEM) and Fourier Transform Infrared spectroscopy (FTIR) for average crystallite size, average particle size, morphology, elemental composition, shape and bond analysis respectively. After analysing the results, the obtained nanoparticles were in the nano range and it has been used in various applications
