摘要：

CdS nanoparticles have been synthesized by chemical synthesis method using ethylenediamine as a capping agent. The nanoparticles were characterized using techniques such as X-ray powder diffraction (XRD), transmission electron microscope (TEM) and UV-Vis absorption spectroscopy. The grown sample is ultrasonicated in ethylenediamine. The dispersed sample is characterized using electron diffraction technique. The optical absorption of the CdS nanoparticles is studied in the range of 200-800 nm. Raman spectroscopy showed that the product were hexagonal wurtzite CdS with the 1(st) and 2(nd) harmonic modes at 300.1 and 601.34 cm(-1) respectively. The optical properties of CdS nano particle were investigated by the UV-Vis-NIR absorption spectroscopy. The band gap of CdS nano particles has been determined.
