Fluorescence characteristics of europium doped phase-separated alkaline earth silicate glass

Abstract

Utilization of phase separation phenomenon is one of the methods which can form interfaces in glass matrix in order to induce the light scattering. The purpose of this study is preparation of europium doped phase-separated alkaline earth silicate glasses, and the investigation of their fluorescence property. With increasing alkaline-earth content and ionic radius of alkaline-earth metal ion, the emission intensity of Eu³⁺ ion increased. The phase separation texture was variously changed due to the composition of glass matrix. It’s considered that fluorescence property of Eu³⁺ ion changes depending on phase separation texture.
