N2 - CdSe thin film was electrodeposited from an aqueous solution of CdSO 4 and H2SeO3 at 75°C on indium tin oxide (ITO)-covered glass substrates. The deposition films were characterized with X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive analysis by X-rays (EDAX), photoluminescence (PL) and UV spectrometry, respectively. XRD analysis shows that the films are exhibit in polycrystalline nature with hexagonal structure. The various mircrostructural parameters such as crystallite size, micro strain, dislocation density and texture coefficient were calculated. SEM study shows that the total substrate surface is well covered by uniformly distributed spherical shaped grains with stoichiometry compositions. Optical transmittance study shows the presence of direct transition with band gap energy 1. 75 eV. A Photoluminescence spectrum of films was recorded and the results are discussed.
