Annealing effect on the Optical Energy Gap and Some Optical properties of )SnO2) 1-x (CO) x films


We have studied the effect of annealing at (550,600) °C on absorption coefficient , optical transmission, Reflectance, optical conductivity and optical energy gap for (SnO2) 1-x (CO) x with (x=0.01) deposited on preheated glass substrates at a temperature of (500 °C) by chemical pyrolysis technique were performed . These films show direct allowed inter band transition that influenced by annealing at (550,600) °C for two hours . From the analysis of the absorption and transmission spectra in the wavelength range (350-900nm). The results show that all these parameters were affected by annealing.
