Chemical tunability of europium emission in phosphate glasses

Résumé

In this study the correlation between bulk chemistry and optical properties for a set of Eu-bearing phosphate glasses, containing different alkali elements, synthetized in air and under NH3 flux, was investigated. The chemistry of the glass strongly influences several properties and the effects of bulk chemistry and synthesis conditions on glass structure and on thermal and optical properties are discussed. In alkali-phosphate glasses studied by absorption and photoluminescence spectroscopy we verified that Eu2+ emission band shifts toward higher wavelengths by substituting the alkali cation (Na
