Abstract
Silica glass containing neodymium is a potentially important laser glass because of its low thermal expansion coefficient and high temperature stability. The sol-gel method is highly advantageous in that it permits the uniform distribution of relatively large concentrations of neodymium in a silica host with respect to conventional processing techniques. In this paper, the evolution of the Nd-doped silica gel as a function of heat treatment temperature, from the liquid state to the glassy state, is discussed. The fluorescence spectra for sol-gel derived neodymia-silica glass is presented. A tentative structural model of the local environment around the neodymium ions in silica glass is presented.
