Abstract

Cadmium indium sulfide (CdIn2S4) thin films were deposited by chemical spray pyrolysis technique on the glass substrate ,and doping by Cu= 1%,3%.5% . The films structure were analyzed by XRD . All the patterns of thin films prepared are polycrystalline .The optical properties are studied by UV-VIS spectrophotometer ,the absorption coefficient was calculated ,its value was more than 104 that supports the direct transition ,the energy gap found between 2.6 eV to 2.85 eV dependent on the ratio of Cu in the thin film. And finally the optical constants such as refractive index ,extinction coefficient, real and imaginary dielectrics were investigated.
