Broadband-NIR Luminescent MgNb 2 O 6 :Cr 3+ transparent glass ceramics fabricated by co-melting and controlled crystallization
Heat accumulation and severe light scattering limit the applications of near-infrared phosphor-converted LEDs (NIR pc-LEDs) in the high-power field. Replacing phosphor encapsulation with Cr3+-doped glass-ceramics (GCs) provides an effective solution. However, obtaining transparent GCs with high thermal quenching re...
