The spectral characteristics of photoconductivity for Bi2O3 thin films were investigated. The films were prepared by thermal oxidation in air of Bi evaporated films. As revealed by X-ray diffraction and polarizing microscopy studies, polycrystalline and multiphasic films were obtained. From the photoconductivity spectral curves, the bandgap energy values were determined, by using the Moss criterion. The influence of oxidation (preparation) conditions on the Eg values is discussed. The photoconductivity of Al-Bi2O3-Al, Cu-Bi2O3-Cu and Al-Bi2O3-In2O3 structures is also investigated. |
