Fe3+-doped MgGa2O4 (MGO: Fe3+) spinel-type phosphors are promising near-infrared (NIR) luminescent materials because of its non-toxic, good thermal stability and adjustable emission. Unfortunately, the existence detrimental oxygen defects in host lead to unsatisfactory luminescence efficiency. In this study, an vacancy repairing engineering has been innovatively developed via Li+ substitution MGO: Fe3+ for significantly enhancing NIR emission 709 nm maintaining outstanding stability. The intensity internal quantum efficiency Li-repaired enhanced 130 % 156% times compared that Fe3+, respectively. This study demonstrates innovative strategy enhance photoluminescence yield MgGa2O4-based infrared by reducing vacancies through cation repair route.

Abstract Long‐wavelength near‐infrared (NIR) phosphors (1000–2000 nm) have shown great promise in intelligent NIR spectroscopy technology fields. However, developing capable of directly absorbing blue light and emitting over 1000 nm still remains a significant challenge. Here, series ultra‐broadband with emission peaks longer than 1500 is achieved by incorporating single activator Ni 2+ ion into ALaMgMO 6 (A = Ca, Sr, Ba; M Sb, Nb, Ta) double perovskite hosts. Significantly, through composition modulation strategy, the designed exhibit an intense absorption band centered at 440 nm, making these mono‐doped pumped commercial LED chips without strictly introducing sensitized ions or energy transfer process. The origination effective blue‐light excitable NIR‐II to NIR‐III phosphor unraveled Rietveld structural refinement local symmetry analysis. Additionally, developed demonstrated potential spectroscopic analysis, night‐vision technology, non‐destructive visualization, information encryption identification. This work provides feasible strategy solve problem that ‐doped cannot be can promote development more long‐wavelength materials for multiple photonic applications.
