Monolithic and transparent Sn-doped SiO2 glasses, where Sn atoms replaced Si centers in the SiO2 network, were prepared by a new sol-gel route by using tetraethoxysilane (TEOS) and dibutyltindiacetate (DBTDA) as precursors.

Abstract
Monolithic and transparent Sn-doped SiO2 glasses, where Sn atoms replaced Si centers in the SiO2 network, were prepared by a new sol-gel route by using tetraethoxysilane (TEOS) and dibutyltindiacetate (DBTDA) as precursors. The maximum amount of Sn doping was 1.40 wt % SnO 2/(SnO2+SiO2) (corresponding to 0.55 mol %). At higher tin content (≥ 1.60 wt %, corresponding to 0.64 mol %) crystalline nanosized particles of SnO2 (6-10 nm) segregated in silica matrix
