Tunable white light emission from glass-ceramics containing Eu2+, Tb3+, Eu3+ co-doped SrLaF5 nanocrystals

Résumé

The Eu2 +/Tb3 +/Eu3 + co-doped fluorosilicate glass ceramics containing SrLaF5 nanocrystals were prepared. XRD results showed the rare earth ions were enriched into the precipitated nanophase. It deduced efficient energy transfers (ET) from Eu2 + to Tb3 + and Eu3 + and intense warm white luminescence of the glass ceramics. Comparing the glass, the luminescence quantum yield (QY) of the glass ceramics was enlarged by about 3 times. That demonstrated the potential WLED application of the present glass ceramics.
