摘要：
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.
