Two-Site Occupation for Exploring Ultra-Broadband Near-Infrared Phosphor—Double-Perovskite La 2 MgZrO 6 :Cr 3+
Xiamen University · China Jiliang University
Abstract
The near-infrared phosphor-converted light-emitting diodes (NIR pc-LEDs) have great potential in food industry and medical fields. For applications based on NIR spectroscopy, the next generation of NIR pc-LEDs is in a high demand of a spectrum with a much broader full width at half-maximum (fwhm), which triggers the discovery of novel broadband NIR phosphors. In this work, the Cr3+-doped La2MgZrO6 (LMZ) was successfully synthesized by a conventional solid-state method in a reducing atmosphere, and the double-perovskite oxide LMZ with two distorted octahedral sites finally led to an ultra-broadband Cr3+ emission centered at 825 nm with an extremely large fwhm of 210 nm and an internal quantum efficiency of…
