摘要：

Cr3+-activated near-infrared (NIR) phosphors have great potential in plant lighting, noninvasive detection, iris recognition, etc. Herein, an aluminoborate host material with a wide band gap (E-g = 4.60 eV) and high Debye temperature is selected to prepare a NIR phosphor Al5BO9: Cr3+ (ABO: Cr3+). The phosphor exhibits typical intermediate crystal field luminescence and has a high degree of matching with plant phytochrome. The photoluminescence intensity at 150 degrees C retains 91.1 % at room temperature. In addition, the spectral redshift (730 nm-770 nm) is achieved through the crystal field ...
