Phase separation and luminescence of Eu_2O_3 doped boron silicate glass

摘要

EU_2O_3 doped boron silicate glass appearing phase separation have been prepared and characterized. The heat treatment temperature was determined by DTA, the microstmcturc and optical properties of the glass were studied by SEM and fluorescence spectra. The adding of EU_2O_3 restrained the phase separation and crysta;;ization of the glass. Eu ions exist in the glass samples as the Eu~(3+) ions, rather than the Eu~(2+) ions. As the heat treatment temperature increases, the phase separation region increased gradually, and the luminescent intensity increases.
