Nitridated Ca(2)NaMg(2)V(3)O(12): Eu(3+) Vanadate Garnet Phosphor-in-Glass
In this study, Ca(2)NaMg(2)V(3)O(12) coordination compound undoped and doped with Eu(3+) obtained in the air and ammonia atmosphere by solid-state reaction was investigated. Ca(2)NaMg(2)V(3)O(12): Eu(3+) obtained in the ammonia atmosphere was then investigated as a phosphor-in-glass (PiG). Annealed...

description | In this study, Ca(2)NaMg(2)V(3)O(12) coordination compound undoped and doped with Eu(3+) obtained in the air and ammonia atmosphere by solid-state reaction was investigated. Ca(2)NaMg(2)V(3)O(12): Eu(3+) obtained in the ammonia atmosphere was then investigated as a phosphor-in-glass (PiG). Annealed Ca(2)NaMg(2)V(3)O(12): Eu(3+) phosphor forms a single phase with the cubic garnet structure and Ia3d space group. Nitridation in ammonia causes a widening of a VO(4)(3−) group emission band on the low energy side and it red-shifts by 20 nm. The emission of Eu(3+) is extended as compared to the non-nitridated phosphor. Ca(2)NaMg(2)V(3)O(12): Eu(3+) after nitridation shows higher emission quantum yield (QY): 49 vs. 45 and lower correlated color temperature (CCT) and 4179 vs. 4998 as compared to phosphor without nitridation. The QY for PiG is 55. The thermal stability of nitridated phosphors is superior to phosphor obtained in the air atmosphere and is further enhanced for PiG. |
