Abstract

Highly transparent nano-sized Zn_xCd_1-xS thin films have been prepared by chemical bath deposition (CBD) technique. In this paper investigations made on the preparation, characterization and photo luminescent (PL) studies of copper doped Zn_xCd_1-xS films are presented and discussed. The deposited films are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and PL spectroscopic techniques. The results of XRD and SEM studies exhibit the average grain size to lie in nano range. The results of optical absorption spectra recorded in the wavelength range 400 - 700 nm, the band gap value is calculated to be ~ 2.57 eV. The PL emission intensity is observed to be maximum for a particular concentration of copper acetate and it almost seizes thereafter.
