Description
Summary:An optical quality silica glass doped with Er^sup 3+^, Yb^sup 3+^ and Lu^sup 3+^ ions is synthesized by the sol-gel method. Virtually unavoidable clusterization of rare-earth elements that occurs upon introduction of lanthanide salts into a sol-gel system and leads to concentration quenching of luminescence of the glass is eliminated through the use of rare-earth phosphate complexes that are chemically bound to the SiO^sub 2^ network. This makes it possible to obtain a nearly molecular distribution of rare-earth elements in the glass matrix.[PUBLICATION ABSTRACT]
