Broadband sources of near-infrared (NIR) radiation have garnered considerable attention in medical applications and non-destructive analysis. In this work, we have synthesized a lithium zinc stannate phosphor Li1.6Zn1.6Sn2.8O8:Cr3+ (LZSO:Cr) for broa

Near infrared to near infrared (NIR–NIR) photo-stimulated persistent luminescence (PSPL) has shown excellent potential in high-resolution bioimaging for deep tissues. However, the PSPL in NIR-Ⅱ region (900–1700 nm) is still lacking. In this wor

Publikováno v: Inorganic Chemistry Frontiers. 7:2313-2321

Cr3+-Doped phosphors are attracting attention for broadband near-infrared (NIR) applications. However, some mechanisms are still unclear due to the entangled crystallographic site occupancy and changeable valence of chromium in the host lattice. In t
