| Résumé |
|
A color-tunable phosphor Li2SrSiO4:Eu2+,Eu3+,Ce3+ (LSSO:Eu2+,Eu3+,Ce3+) was synthesized by solid state reaction in reducing atmosphere followed by a controlled heating in air at different temperatures. Due to the different sensitivities to oxidation of the Eu2+ and Ce3+ ions, the emission centers Eu2+/Eu3+/Ce3+ can coexist in the Li2SrSiO4 host and enable a tunable coloration of the "blue-yellow-red" photoemission. By controling the energy transfer between the different activators, a single phase white phosphor was obtained.
