Abstract

This paper compares the luminescence spectra of Eu3+ in sol-gel derived silica samples heated at different temperatures, following the densification process from wet gel to compact silica glass. Lifetimes, linewidths, and Stark splittings of the transitions were used to study the structural evolution of the gel network.
