A near Infrared (NIR) quantum cutting (QC) Sr3AlO4F:Tb3+,Yb3+phosphor was synthesized by the conventional high temperature solid-state reaction. The luminescence spectra both in visible (VIS) and NIR regions and decay lifetime curves of Tb3+have been measured to prove energy transfer (ET) from Tb3+to Yb3+. Quantum efficiency (QE) related to Yb3+concentration was calculated and the highest QE was found to be 135% hen Yb3+doped concentration at 20%. The present Tb3+and Yb3+co-doped Sr3AlO4F phosphor may be a promising candidate to modify the spectral of the solar light.

Cr[Formula: see text]-doped zinc gallate (ZnGa2O4) near-infrared (NIR) phosphors were synthesized via a high temperature solid state method. The luminescence properties of the phosphors were studied systematically. A significant spectra overlap between the emission of ZnGa2O4 and the absorption of Cr[Formula: see text] was observed and 300 nm excitation exhibited the most excellent long-lasting luminescence properties among the three main excitation bands. Luminescence intensity was changed with the ratio of Ga[Formula: see text]/Cr[Formula: see text] and the blue host emission of ZnGa2O4 was suppressed when doping Cr[Formula: see text] into ZnGa2O4. The fluorescence decay curves of blue emission of ZnGa2O4 with different Cr[Formula: see text] doping concentrations indicated that the lifetime of ZnGa2O4 at 505 nm become shorter with the increase of the Cr[Formula: see text] concentration. Herein, a possible mechanism of long-lasting luminescence in ZnGa2O4: Cr[Formula: see text] was proposed that the NIR long-lasting luminescence in ZnGa2O4: Cr[Formula: see text] comes from the persistent energy transfer from ZnGa2O4 to Cr[Formula: see text].
