Glass with nanosized occlusions of bismuth selenide

The composition of oxide silicate glass and the modes of its synthesis and heat treatment, at which nanocrystals of bismuth selenide are formed in the glass, have been found. Three different methods: X-ray diffraction analysis, Raman scattering and electron microscopy identified the crystalline phase of bismuth selenide nanocrystals with a characteristic size of about 20 nm. The data on the absorption spectra of the obtained glass samples in the range of 400 - 3300 nm are also presented.
