Preparation and fluorescent properties of rare earth containing high silica glass

Abstract

The porous glass was impregnated with rare earth ions, and then sintered at 1100°C. The fluorescent property of the rare earth ions contained in high silica glass was investigated. It was found that the Ce³⁺ and Eu²⁺ ions in the glass exhibit very strong luminescence. The kind of atmospheres during sintering influences the fluorescent property greatly.
