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].

Short Range Structure

The oxyhalides Ba2InO3F, Ba2InO3Cl, and Ba2InO3Br were synthesized using the solid state method. It was found that the increasing of halide ion radius leads to the increase of lattice parameters and also caused to redistribution of indium-oxygen bond lengths. The possibility of water uptake was proved by thermogravimetry measurements. The presence of different forms of oxygen-hydrogen groups in the structure of hydrated oxyhalides was indicated by infrared spectroscopy.
