Abstract — The basic aim of this research work is to present the synthesis of ZnSe thin film, by varying doping concentration of selenium oxide on ITO plate using a relatively simple and low cost traditional electrodeposistion technique. The physical properties obtained are similar to that reported earlier. The compatibility of the room temperature ZnSe thin films for structural, optical properties are investigated by using the techniques, X-ray diffraction (XRD), FTIR, UV-Vis spectroscopy, and morphological studies are analysed by using scanning electron microscope, (SEM). The crystallite size was calculated ranges from 30-40 nm, and band gap values are nearly equal to 2.2 eV, the selenium oxide concentration increases the band gap of the value is also increased to minimum value. The optical band gap is found to be particle size dependent and increases with increasing Se content or it is increasing with decreasing particle size. Keywords-- ITO plate, selenium oxide, band gap I
