AB  - Thin films of Se-CuSe2  of three different thicknesses have been prepared by vacuum evaporation method on a glass substrate at room temperature. Surface morphology was investigated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The structural characterization of thin film was investigated using Xray diffraction pattern (XRD). The presence of twophase system is observed. One is the solid solution of Cu in Se and the other is lowpressure modification of CuSe2 . The optical properties of the films were investigated by photoluminescence spectroscopy and UV-VIS spectroscopy. CuSe2  exhibits both direct and indirect transitions. According to UV-VIS measurements, the band gap for direct transition is found to be in the range of 2.72–2.75 eV and that for indirect transition is in the range of 1.71–1.75 eV. On the other hand, selenium exhibits direct band gap in the range 2.33-2.36 eV. All estimated band gaps slightly decrease with the increase of the film thickness. Photoluminescence spectra of thin films show emission peaks at about 1.6 and 2.3 eV nm at room temperature, with no observed shift with decreasing temperature. A model is proposed for explaining such anomaly
