Synthesis and Characterization of Mn Doped CdS Nanoparticles Prepared by Chemical Bath Deposition Method

U. S. Patle

Abstract: In this paper, synthesis and characterization studies of nanocrystalline CdS semiconducting particles grown on the glass substrates by means of chemical bath deposition method has been reported. Mercaptoethenol (capping agent) were added in different concentrations in order to limit the growth of the particles and control their sizes. UV-VIS optical absorption studies and Scanning electron microscopy images indicate that the volume of capping agent adjust the band gap of CdS to obtain stable and homogenous films. Band gaps are found to increase and article size is found to be in nano range from optical absorption studies. The present paper discuss the optical properties of semiconductors nanocrystal are strongly dependent on particles size.
