Abstract

Using methods of IR transparency spectroscopy in a range of 1200 – 200 cm-1 and diffuse reflectance spectroscopy in a range of 200 – 2500 nm the character of interaction in the systems Ge-In2O3, Ge-In2SnO5, Ge-LnInO3 (Ln - La, Sm, Eu) is investigated. Essential change in spectral characteristics of systems with the appearance of new bands and disappearance of previous ones is established at annealing of composites of Germanium - metal oxide composition which confirms the fact of oxidation-reduction interaction between components with formation of volatile products, mainly In2O and GeO. Thermodynamic calculations well coincide with experimentally established values of conditional temperatures of evaporation. Systems are perspective for obtaining thin-film coatings interference optics of a IR range of a spectrum.
