Indium oxide film is deposited by reactive evaporation of indium in the presence of oxygen gas onto an unheated glass substrate. It was found that thickness of the film and partial oxygen pressure during the deposition affects the optical propedies of the indium oxide thin film. We studied the optical band gap for different thickness and partial pressure keeping a comtant annealing temperature. It was found that the band gap varies from 3.5-3.8 eV, as thickness of the film increased. The band gap energy had also shows the similar trend and it was also studied as a function of annealing temperature. A systematic investigation of the optical band gap as a function of thickness and oxygen partial pressure at dfferent annealing temperature was carried out.
