Abstract
Abstract Near‐infrared phosphor‐converted light‐emitting diodes (NIR pc‐LEDs) are regarded one of the most promising light sources for food analysis, plant growth, bioimaging, night vision, and so on. Cr 3+ ‐activated NIR phosphors have garnered increasing attention due to their exceptional photoluminescence properties for NIR pc‐LED. However, most of them suffer from poor thermal stability or low efficiency which limits their large‐scale application. Herein, a novel Sr 3 MgGe 5 O 14 : Cr 3+ (SMGO: Cr 3+ ) NIR phosphor is presented, which exhibits a broadband NIR emission ranging the range of 650–1000 nm with a peak at 735 nm. SMGO: 0.005Cr 3+ phosphor demonstrates an almost near‐unity internal quantum…
