Design of broadband near-infrared Y0.57La0.72Sc2.71(BO3)4:Cr3+ phosphors based on one-site occupation and their application in NIR light-emitting diodes

A novel broadband near-infrared Y 0.57 La 0.72 Sc 2.71 (BO 3 ) 4 :Cr 3+ phosphor based on one-site occupation was designed by introducing a distorted octahedral structure.
