Abstract:

The energetic, structural and electronic properties of CdS with different nanometer sizes were prepared by the precipitation method by changing the refluxing time of the reactants. The grain sizes were determined by X-ray diffraction method. By impedance analyses method, the band gap value of nanoparticles were calculated and compared with the bulk material. The nanocrystalline CdS was characterized by Impedance spectroscopy and corresponding measurements are discussed briefly in this paper.
