摘要：

Thin films of Fe2O3, FeS2 and FeS have been prepared by the method of chemical spray pyrolysis. The absorption and transmission spectra are recorded for different thicknesses of these films. The spectra are analysed and the direct band gaps, the indirect band gaps, both allowed and forbidden, the forbidden direct band gaps and other optical parameters are all investigated.
