تاثير التشويب بالانتمون علي الخواص البصرية لاغشية (SnO2) الرقيقة

In this work we are studied the optical properties for pure (SnO2) and doped with antimony with a temperature ( 550 C° ) and calculated the optical parameters as refractive index , extinction and absorption coefficient. The result showed that all thin films are of polyctystalline structure. The value of the forbidden energy gap for direct transitions were found to be increase as the doping percentage increased. While the value of the forbidden energy gap for indirect electrical transitions were found to be decrease as the doping percentage increased except for (1%) doping . The calculated results exhibit an a good agreement with the published results.
