Interaction Studying in System GeO - B2O3 by Spectroscopic Methods

Abstract

Because of X-ray amorphous character of GeO and B2O3 for study of interaction between them methods of IR transmission spectroscopy and spectroscopy of diffuse reflectance are applied. Essential change of positionand intensity of bands of absorption in system GeO-B2O3 (H3BO3) at heating and thermal evaporation in vacuum is established. It is observed essential gypsochromic shift of short-wave border and bathochromic shift of long wave border of domain of an optical transparency of a coating compared with initial GeO that testifies in favour of change of the nature of a material. A coating from Germanium (ІІ) oxide exhibits high optical and operational parameters and are perspective for interference optics of an IR range of a spectrum.Keywords: Germanium (ІІ) oxide, Boron oxide, spectroscopic methods, thin-film coatings.
