Cr3+-activated broadband near-infrared (NIR) emitting phosphors have attracted more attention worldwide as they are strongly expected to be promising light convertors for phosphor-converted NIR light sources for NIR spectroscopy and imaging technologies. Unfortunately, few works have reported the co-existence of multi-valence Cr ions and its negative effects on the luminescence efficiency of the Cr3+ ion in NIR emitting phosphors. Herein, we systematically investigated and prove the existence of Cr6+ ions in novel LiInO2:Cr3+ NIR emitting phosp...
