Glass Physics and Chemistry
The alkaline antimony-phosphate glass doped with Nd3+ was synthesized under different conditions with the controlled content of OH groups. The Nd2O3 concentration varied in the range of 0.2–2.0 mol %; the Sb2O5 concentration was 20 mol %. The absorption and Nd3+ ion luminescence spectra and the absorption spectra of OH groups were obtained. Quenching of the Nd3+ ion luminescence depending on the Nd2O3 and OH group concentrations was studied. It was found that the optimized spectroscopic and kinetic parameters of glass (emission cross section, emission width, radiative lifetime) are close to the parameters of the SCHOTT GLAS industrial laser glass. It was shown that the immediate environment of Nd3+ ions is formed by phosphate polyhedra. © 2015, Pleiades Publishing, Ltd. Source
