CdIn₂Se₄ thin films were prepared by a thermal evaporation technique on
glass and quartz substrates. The influence of substrate temperature on the
structural and optical properties has been studied. The crystal structure and
orientation of the prepared films were investigated by x-ray diffraction and
observed that CdIn2Se4 corresponds to cubic crystal structure. The variation in
crystallite size with substrate temperature were studied and observed an
increase in crystallite size with substrate temperature.
