Thermally stable NIR broad emission of Cr 3+ doping phosphor with a high output power

The anti-thermal quenching of Cr 3+ is determined by the attribution of the defect level, which originates from the coupling between the doped ion Cr 3+ and the V O . NIR pc-LED achieves an NIR output power of 59.67 mW with working current of 150 mA.
