Abstract

Highly adhesive bismuth oxide thin films on glass have been prepared by air oxidation of vacuum evaporated bismuth thin films at various temperatures. The transmittance, optical band gap, refractive index and adhesion show temperature and oxidation time effects. The films show a direct band gap between 2 and 2.5 eV. The refractive indices are in the range 1.854–1.991. The transmittances of the bismuth oxide films are quite high in a large wavelength range. These bismuth oxide films can have potential use in optical waveguides.
