Phase Separation and Luminescence of Eu₂O₃ Doped Boron Silicate Glass

Abstract:

Eu₂O₃ doped boron silicate glass appearing phase separation have been prepared and characterized. The heat treatment temperature was determined by DTA, the microstructure and optical properties of the glass were studied by SEM and fluorescence spectra. The adding of Eu₂O₃ restrained the phase separation and crystallization of the glass. Eu ions exist in the glass samples as the Eu³⁺ ions, rather than the Eu²⁺ ions. As the heat treatment temperature increases, the phase separation region increased gradually, and the luminescent intensity increases.
