摘要
Abstract
In order to overcome the shortcoming of ( Sr, Ca) AlSiN3∶Eu2+red phosphor on the ther-mal quenching and long term anti-degradation, which results in obvious light efficiency decay and color shift and have adverse impact on the light quality of white LED, in this paper, alkaline earth metal ions and rare earth metal ions are doped into ( Sr, Ca) AlSiN3∶Eu2+ red phosphor and their influence on the thermal quenching and long-term performance are explored. The results show that the doping Li+-Dy3+, Li+-Ho3+ ion can play important role to promote the anti-degradation per-formance effectively, and suppress the color shift during long term aging simultaneously.关键词
