Abstract

Bismuth trioxide and antimony trioxide were deposited by thermal vacuum evaporation one on top of the other. The temperature of the substrate during deposition was maintained at 200 C, 700 C and 1200 C, respectively. Also, the deposition order of the two oxides was reversed, in order to find if there is any change in the properties of the entire two oxides structure. Their structural characteristics were studied by means of X-ray diffraction and compared to literature. The optical transmission spectra were also studied by means of the Swanepoel and Wemple-DiDomenico methods. Clear correlations between the optical behavior and the structural changes were noticed..
