Near-infrared phosphor-converted light-emitting diodes (NIR pc-LEDs), a widely used NIR light source, are typically prepared by sealing the phosphor powder and an LED chip with epoxy resin. One issue that pc-LEDs frequently encounter is aging deterioration of resin over time, which leads to self-absorption sharp decline in emission efficiency. Here, we report synthesis chemically stable luminescent material composed Cr3+-doped Ba2NaNb5O15 nanocrystals measuring 10-15 nm, Cr3+ ions located octahedral centers nanocrystals. Under 460 nm excitation, transparent glass-ceramic exhibited broadband range 600-1400 originated from electronic transition excited state 4T2 ground 4A2. The peak was at ∼810 FWHM ∼230 internal quantum efficiency reached ∼0.81%. We constructed pc-LED device using optimized NIR-emitting glass-ceramics commercially available blue chip, demonstrating its promising application night-vision lighting. Our study provides basis for preparation glass-ceramic-based devices as improved alternative solid-state illumination.
