Fabrication and Characterization of CdS Nanoparticles Obtained via Microwave- Assisted Synthesis

In the present study a rapid microwave heating method was used to prepare CdS nanoparticles. The morphology, structure and composition of the prepared CdS were examined by means of Field-Emission Scanning Electron Microscopy and X-ray diffraction. The optical properties of the CdS thin films deposited onto glass substrates were investigated by means of UV/Vis spectrophotometric measurements. It has been found that the size and structure of CdS particles synthesized by rapid heating irradiation depend on the alkalinity of reaction mixture and microwave power. The synthesized CdS nanoparticles have a band gap of 2.5 – 2.7 eV
