Abstract : Chemical method has been used to prepare cadmium sulphide films by using cadmium chloride (CdCl), Amonia (NH3) and thiourea (CSNH2).The effect of the temperature of preparing solution over the range of (40-80oC) have been Adapters studied, it show that increasing of the solution temperature will increase the reaction speed and change the film color to more orange side.The optical properties over the wavelength range (400- Binocular Harness 700)nm were recorded before and after annealing of prepared film at 300oC for 30 mint, so the calculated energy gap was about (2ev).
