【 摘 要 】

Spray pyrolysis is simple and inexpensive method to prepared thin films on large area. CuInTe2(1-x) S2x thin films were deposited by this method. Optical band gap was determined for composition parameter x from the transmittance study at room temperature. Optical band gap increases as composition x increases and it is varying linearly with composition. The lattice parameter a and c were calculated for all composition x from the Philips X-ray diffractometer. The structure remains tetragonal chalcopyrite throughout the composition x with preferred orientation along 112 direction. Tetragonal distortion is very small and negative indicating dilation (c>2a) rather than compression
