Preparation of BaSi2O5:Eu2+ glass ceramic phosphors and luminescent properties

Abstract

EU2+-doped BaSi2O5 glasses were prepared by melting method and the glass-ceramics (GCs) were obtained by heat-treatment at various temperatures between 800 °C and 1000 °C. The single phase of BaSi2O5 micro-crystal precipitated in the GCs by heat-treatment above 950 °C, and the quantum yield (QY) of Eu2+ fluorescence became higher than that of other GOs, in which other crystal phases precipitated. When the BaSi2O5 precipitated, the QY increased drastically.
