High Output Power and High Quantum Efficiency in Novel NIR Phosphor MgAlGa0.7B0.3O4:Cr3+ with Profound FWHM Variation

phosphor, exhibiting a remarkable NIR output power of 136 mW at 600 mA in ultra-broadband NIR pc-LEDs. This study describes the preparation of highly efficient phosphors and provides a further understanding of the tunable FWHM, which is vital for high-performance NIR phosphors with versatile applications.
