Near-infrared (NIR) light-emitting diodes (LED) have garnered significant research attention worldwide. This presents a novel near-infrared phosphor doped with Pr3+ ions, exhibiting broad NIR emission ranging from 800 to 1100 nm. Under 450 nm excitation, Li3Cs2Ba2B3P6O24:Pr3+ material generates bands peaking at 882 and 1038 However, this exhibits relatively lower luminous intensity. Through Eu2+ co-doping, the intensity of is significantly enhanced due energy transfer. Photoluminescence spectra luminescence decay curves support efficient transfer (ET) between Pr3+, resulting in remarkable luminescence. The study evaluates temperature stability practical application Li3Cs2Ba2B3P6O24:Eu2+, LED applications. Consequently, ions emerge as an alternative emitter though Eu2+, offering new insights into developing light sources for broadband pc-LED

Abstract The performance of the near‐infrared phosphor‐converted light‐emitting diodes (NIR pc‐LEDs) mainly depends on NIR emitting phosphors used. Cr 3+ doped materials can be excited by blue light chips, but their emission is located in NIR‐I region (650–1000 nm). Ni 2+ are NIR‐II (1000–1700 nm), they cannot effectively chips. Herein, , mono‐doped, and co‐doped Sr 2 GaTaO 6 prepared investigated. ions occupy two octahedral sites Ga Ta 5+ . co‐doping has achieved breakthroughs. One to shift optimal excitation wavelength from violet due energy transfer (efficiency up 70%) other achieve broadband continuous across regions (650–1700 nm, with a full width at half maximum (FWHM) 410 nm (173 + 237 nm)). : 0.02Cr 0.01Ni phosphor combined commercial 460 chip realize its application organic compounds identification, night vision, biological imaging. This work points out direction for future development efficient super NIR‐emitting phosphors.
