| description |
Chemical spin coating is used to prepare pure and indium doped thin films of tin dioxide. All pure and doped thin films have been annealed at a temperature of 500oC. The effects of indium doping and alpha irradiation on the optical properties were studied by recording spectra of transmittance and absorbance at wavelengths (250 - 1250) nm. We found that the transmittance decreases with increasing doping concentrations, while the absorbance increases with increasing doping concentrations, whereas the allowed direct optical band gap decreases with an increase of doping. The results of this study shows that alpha irradiation causes a decrease in the band gap values, and it also effect on the optical properties such as transmittance, absorption coefficient and reflectance.
