SYNTHESIS AND CHARACTERIZATION OF ZINC SELENIDE (ZnSe) THIN FILMS ELECTRODEPOSITED ON ITO AND SnO2SUBSTRATES

The ZnSe thin films were deposited on ITO and SnO2 substrates by modified-electro deposition method. In order to limit the particle size, the growth was controlled by stabilization of nanocrystals in ITO and SnO2. The X-ray diffraction studies, laser Raman vibrational identification and photoluminescence analyses confirmed the formation of nano crystal (ZnSe) in simple cubic phase with a mean crystallite size 20 nm on both substrates. From the optical studies, it was observed that, the blue shift taking place in the optical absorption and the luminescence data is consistent with the reported values.
