Yuefang Qin et al.

Summary: In this work, a tunable broadband NIR phosphor LiScO2:Cr3+ was reported, which exhibited a significant red-shift of emission spectrum by increasing Cr3+ concentration. The emission peak ranged from 807 to 870 nm with a full width at half maximum of 165 nm when excited by 450 nm. The mechanism of tunable emission induced by Cr3+ concentration was investigated through the study of electronic properties, site occupation, local structure, and behavior of Cr3+ ions.
