Cadmium Sulfide (CdS) nano particles are synthesized by chemical precipitation method. Cadmium Chloride and Thiourea are used as the precursor materials. Ammonia water & distilled water are used as solvent. The samples are annealed at 100°C, 300°C and 500°C for 1 hour. Transmission electron microscopy (TEM), Energy–dispersive X-ray spectroscopy (EDAX), and X-ray diffraction pattern (XRD) are used to study the morphologies, distribution, and crystallinity of the CdS nanoparticles and to calculate the values of their sizes. The results indicate that the CdS are formed with Hexagonal structure and the particle size varies with the Cd+2 ions. Synthesized nano particles show structural properties after annealing. The particles are in high degree of crystallization. The XRD results reveal that the annealing effect has increased the crystalline size of the CdS nanoparticles. TEM demonstrates that the average sizes of spherical cadmium sulfide nanoparticles are 73.30 nm, 61.91 nm and 88.81 nm at annealing temperature of 100°C, 300°C and 500°C respectively. In this research CdS has been studied due to its potential technological applications in field effect transistors, solar cells, photovoltaic devices, light emitting diodes, photo catalysis, photoluminescence, infrared photo detector, environmental sensors, biological sensors etc.
