However, at \u223c900 nm, the extensively used solar-like phosphor-converted light-emitting diodes (pc-LEDs) are limited by a lack of high-performance NIR luminescent materials. We report a broadband NIR phosphor Sr<sub>2<\/sub>ScSbO<sub>6<\/sub>:Cr<sup>3+<\/sup>&nbsp;with a double perovskite-type structure, thus simultaneously demonstrating high luminescence efficiency and good thermal stability. Under 550-nm excitation, Sr<sub>2<\/sub>ScSbO<sub>6<\/sub>:Cr<sup>3+<\/sup>&nbsp;demonstrates broadband NIR emission centered at \u223c890nm with luminescence internal\/external efficiencies of 82.0%\/35.7%, respectively. Furthermore, the luminescence integrated intensity at 430 K remains at \u223c66.4% of the initial intensity. We successfully fabricated pc-LED devices using a 465-nm-sized blue chip and other commercial phosphors, presenting a relatively complete solar-like spectrum from blue to NIR light and is expected to be used in solar-like lighting.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sci.
