英文摘要	Broadband near-infrared (NIR) phosphor-converted (pc) LED is promising next-generation tiny light source for smart and broadband NIR spectroscopy technology. However, NIR phosphors suffer from challenges in terms of low quantum efficiency and bandwidth. By selecting a host that has a big bandgap and weakening coupling effect among Cr3+, a novel LiGaP2O7:Cr3+ (LGAP:Cr3+) NIR phosphor that has a high external quantum efficiency (28.3%) is discovered. Under 450nm excitation, LGAP:Cr3+ shows broad NIR emission from 700 to 1100nm with a bandwidth of 170nm. Importantly, the fabricated pcLED demonstrates bright broadband NIR light and an excellent performance in night vision. The results promise the use of the LGAP:Cr3+ phosphor for high-performance broadband NIR LED that employs only one tiny blue LED chip. 2021 Wiley-VCH GmbH
