Differing from traditional near-infrared (NIR) light sources that are made thermal radiation of a blackbody or filtered gas discharge, the technique by converting blue emission light-emitting diode (LED) chips into NIR provides solution. For this purpose, phosphor should be developed at first. In work, we report Zn2InGaO5:Cr3+, synthesized 1450 °C for 5 h in air ambient, applicable LED application low temperature no higher than 200 K. The Zn2In0.98Cr0.02GaO5 and Zn2InGaO5 host have direct band gap about 3.00 3.03 eV, respectively, belong to class bandgap semiconductors. Excited 471 nm room temperature, gives ultrabroadband emission, peaked 826 with full width half-maximum (FWHM) 192 nm, region 700–1100 nm. luminescence intensity increases as 10 K, maximizes then decreases further, showing an anomalous temperature-quenching effect. Meanwhile, peak blue-shifts continuously 779 output power pc-LED device packaged using Zn2InGaO5:Cr3+ driven under current 100 mA is 5.14 mW, which photoelectric conversion efficiency 1.9%.

Abstract Near‐infrared (NIR) phosphors that exhibit high quantum efficiency and excellent thermostability are of critical importance for the development NIR light‐emitting diodes (LEDs) with substantial output power. In this work, Cr 3+ ‐Ni 2+ codoping Y 3 Ga 5 O 12 (YGAO) a internal (IQE), external (EQE), notable thermal stability prepared via solid‐state reactions. When excited by blue light at 437 nm, YGAO:Cr /Ni demonstrate broad intense emission spanning 600–1100 nm 1200–1650 nm. YGAO:3%Cr /0.01%Ni an IQE 96.9% EQE 37.5%, whereas YGAO:6%Cr have 76.2% 36.3%. The luminescence intensities ions 423 K show zero quenching in compared to those 303 K, which is attributed enhancement effect caused electron population between energy levels trap‐supplemented luminescence. LED based on has maximum power 197.79 mW under 1000 mA operating current. Furthermore, also promising potential detection functional groups, night vision, penetration.
