CdS and CdS:Sn thin films were successfully deposited on glasssubstrates by spray pyrolysis method. The films were grown atsubstrate temperatures 300 C°. The effects of Sn concentration on thestructural and optical properties were studied.The XRD profiles showed that the films are polycrystalline withhexagonal structure grown preferentially along the (002) axis. Theoptical studies exhibit direct allowed transition. Energy band gapvary from 3.2 to 2.7 eV.
