摘要

The compact size and high efficiency of near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs) make them promising light sources in various fields, such as miniature NIR spectrometer. However, the current state of NIR phosphors with emission wavelengths exceeding 850 nm shows poor photoluminescence (PL) thermal stability. In this work, we present cubic-phase Sc(PO3)3:xCr3+ (x = 0, 1, 5, 10, 12, 14, 16 and 18 at
