| 摘要 | Ultra-broadband near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs) have great application prospects in research and industrial fields. However, simultaneously achieving highly efficient and ultra-broad NIR emission in phosphor material remains a challenge. Herein, an ultra-broadband NIR emission in the range of 800–1200 nm with ultra-high emission efficiency of up to 64.2% is first achieved by substituting the Sc3+ site in Cs2NaScCl6 perovskite single-crystal with a Cr3+ ion. By combining the experimental results with first-principles calculations, an efficient charge transfer sensitization process from host to Cr3+ is found to be the fundamental reason for the ultra-high NIR emission efficiency. Benefiting from the excellent efficiency and superior chemical resistance to heat and UV radiation, an ultra-broadband NIR pc-LED made of this phosphor demonstrates great potential in biomedical imaging, nondestructive testing, and night-vision devices. © 2023 Wiley-VCH GmbH. |
