Extensive studies are done on semiconductor nano-particles because of their wide applications in opto-electronic devices. Semiconductor nano-crystallites electronic devices have wide variety of optical applications with the advance of science and technology. CdS are grown into ammonia matrix and synthesized by chemical route. Growth of Nano-structured CdS is confirmed by the XRD study. Optical properties of Nano-structured CdS are studied by XRD, SEM, TEM, UV and PL. Average particle size is found to be 2.5nm from SEM the study which is conformed by XRD study. Peaks of photoluminescence (PL) Emission Spectra are found around 295.5nm and 365nm at room temperature. Optical absorption studies were done with the help of a UV-VIS Spectrophotometer, which showed a strong absorbance at wavelength 230nm. X-ray fluorescence study also confirmed presence of Cd & S in the nano structured films.
