| Abstract | ||
| In this research some optical properties of CdS thin films have been studied. CdS thin films were prepared by the method of chemical spray pyrolysis deposition on glass substrates which were heated to (350Cº).The thikness of prepared film was (1400Aº).The absorption and transition spectra were recorded using (uv_visible) spectrophotometer in the range of wave lengths (330_900)nm. It is found that the absorption coefficient was more than(104)cm-1,which indicate that we have adirect allowed transition.Some other optical properties such as energy gap ,transmitlance ,Reflectivity, and extinction coefficient have been studied as afunction of photon energy. | ||
