Abstract

Constructing Cr3+–Cr3+ ion pair luminescence is a promising strategy for developing long-wavelength near-infrared phosphor with a high PLQY for emerging smart spectroscopy applications. Herein, we achieve controllable Cr3+–Cr3+ ion pair coupling in K2Zr1−δTiδAl(PO4)3:Cr3+ (0 ≤ δ ≤ 1) solid-solutions, enabling a systematic study of coupling-strength-dependent luminescence performance.
