Fe2O3 thin films were deposited on glass substrate by chemical spray pyrolysis (CSP) technique at a temperature of 450 o C.X-Ray diffraction indicates that the films were polycrystalline with a dominant peak along (100). Surface morphology was studied using atomic force microscope (AFM). The grain size values were observed in the zone of (72.46), (71.53) and (59.87) nm for the (Fe2O3, Fe2O3:1% B, Fe2O3:3% B) respectively. Transmittance spectra were recorded to obtain the optical characterizations like absorption edges, which was shifted toward long wavelength. The optical bandgap shows a decrement in their values from (2.65 to 2.45) eV byB doping.
