摘要

采用等摩尔Ca2+和Zr4+掺杂制备了新型石榴石型Gd3-xCaxAl2.95Ga2-xZrxO12:0.05Cr3 + (x= 0-2.0)远红（FR）荧光粉。量子效率和温度相关发光分析成功制备出最佳的x=0.5荧光粉，该荧光粉在~714 nm处表现出高效率（IQE=92.8%， EQE=31.6%）的宽带fr发射峰（半峰宽~81 nm）和在450 nm光激发下优异的热稳定性（95.5%@423 K）。其性能远远优于大多数报道的Cr3+活化的FR发光石榴石荧光粉，并且其发射光谱与远红色光敏色素的吸收带可以很好地叠加，使得该荧光粉在构建用于植物照明的高质量FR pc-LED中具有巨大的应用潜力。

Achieving high-performance far-red emission in Cr3+ activated garnet phosphor via Ca2+/Zr4+ doping toward plant lighting

Equimolar Ca2+ and Zr4+ doping was implemented to establish novel garnet-type Gd3‒xCaxAl2.95Ga2‒xZrxO12:0.05Cr3+ (x=0‒2.0) far-red (FR) phosphors. The quantum efficiency and temperature-dependent luminescence analysis successfully produced the optimal x=0.5 phosphor, which exhibited highly efficient (IQE=92.8%, EQE=31.6%) broadband FR-emission peaking at ~714 nm (full-width at half-maximum ~81 nm) and excellent thermal stability (95.5%@423 K) under 450 nm light excitation. Its performance is far superior to that of most reported Cr3+ activated FR-emitting garnet phosphors, and the emission spectrum can well superpose with the absorption band of the far-red phytochrome, making this phosphor have huge potential application in the construction of high-quality FR pc-LED used for plant lighting.
