Paper Abstract

Optical materials prepared by the sol-gel process are of current technological interest. Sol-gel silica glasses doped with rareearth (RE3+) ions are an important class of optical materials with applications including solid-state lasers, optical waveguides, fiber amplifiers and devices for optical communications. In this paper, we describe the preparation of rareearth- doped silica-gel glasses and discuss the infrared properties of silica structure as a function of heat treatment. The samples were prepared from tetraethoxysilane (TEOS), water, ethanol, fumed silica and soluble in a water or ethanol the salts ofthe RE3+(Er3+,Nd3+,Sm3+,Pr3+,Eu3+) elements.
