. The corresponding SWIR pc-LED delivers a high SWIR output power of 169.2 mW@350 mA, significantly outperforming the commercial devices. Finally, advanced palm vein recognition and portable non-destructive detection are successfully demonstrated. This study provides new insights and an effective materials platform for developing high-performance SWIR-emitting materials toward advanced photonic applications.
