摘要
As a very important component of NIR spectroscopy, the enhancement of luminescent efficiency and the broadening of bandwidth for NIR light sources are still considered to be a challenge. Hereon, a novel Cr3+-doped MgO-Al2O3-SiO2 multi-phase glass-ceramics was successfully constructed. Upon excitation of 400 nm, the glass-ceramics presented an ultra-broadband NIR emission peaking at-910 nm with full width at half maximum of >270 nm, and the internal/external quantum efficiency of 60.4 %/28.8 %. The integrated emission intensity remained at similar to 86.6 %/80.9 % at 100 C-degrees/150 C-degrees compared to the intensity at room temperature. Furthermore, a NIR device was made by encapsulating the glass-ceramics on 405 nm LED, which presented a NIR output power and photoelectric conversion efficiency of 322 mW/1117 mW and 2.72 %/2.39 % at the driven current of 100 mA/320 mA, respectively. This work realized simultaneous adjustment of luminescent efficiency and bandwidth by selective enrichment of Cr3+ ions into different crystal phases, which provides an effective strategy for improving the luminescent efficiency and bandwidth of NIR glass-ceramics.
