Structural and optical properties of the bismuth-containing quartz-like glasses

Abstract

Bismuth-containing quartz-like glasses (BCQGs) were synthesized by an impregnation of the silica porous glasses (PGs) with Bi(NO3)3 aqueous solution. Then the samples were sintered at the temperatures T from 700 °C to ≥ 1500 °C up to closing the pores. Characterization of BCQGs was carried out using the UV-VIS-NIR spectroscopy and IR spectroscopy. The absorption and luminescence properties of the BCQGs are discussed. It is shown that the growth of absorption in the short-wave region is characteristic for BCQGs. IR spectra confirmed the presence [BiO3] and [BiO6] units and α - Bi2O3 phase in BCQGs. The spectral dependences of the luminescence and excitation of the luminescence of the synthesized glass depending on their thermal prehistory were investigated. For the first time, 3dimensional luminescence spectra have been obtained for BCQG.
