Vacuum evaporated thin films of indium phthalocyanine chloride are prepared at room temperature. Post evaporation annealing is done at temperatures of 353 K, 403 K, 453 K and 503 K. The electrical conductivity and optical absorption spectra of these films are studied. From the optical absorption spectra, over a wavelength range of 200-900nm, the optical energy band gap Eg is calculated. A decrease in Eg is observed with an increase of annealing temperature. The thermal activation energy, Ea, is not notably affected by annealing. It is found that Ea is varied with a change in thickness of the film
