A new thermal degradation mechanism of red Sr2Si5N8:Eu phosphor: From the view of microstructural evolution

Nitride red phosphors of Sr2Si5N8:Eu2+ are synthesized in mild conditions and exhibit excellent luminescence properties; yet, the occurrence of thermal degradation results in a decrease of their luminous intensity and quantum efficiency at the high working temperature of wLED. This work shows that S...
