AbstractCd2SnO4 thin films have been prepared by Spray pyrolysis on glasses slides of ( 0.2 M ) from (CdCl2.2H2O) and (0.2 M,0.1 M)from(SnCl4.5H2O) . Some films are prepared in different temperatures ( 543,583,703) k , also some samples are prepared in two flow rates of gases(24,27) ml/min and other samples are prepared (Cd:Sn) in different volume concentrations(1 : 1,2 : 1). The optical measurements show that the
films have high transmition in the visible region such that there will be transmition materials if the transmition reached to (97%) at (900 ) nm wave length. In addition , the Absorption coefficient ,Extinction coefficient and energy gap change as a result of the changing the preparation conditions for the films , like ( temperature degree of
deposition substrate , flow velocity of sputter gas , molarity concentration and volume percentage for contains deposition solution) .
