AbstractCubic garnets activated by neodymium and holmium, Li_6CaLa_2Nb_2O_12:Nd^3+,Ho^3+, were obtained by solid-state method. The main regularities of changes in the luminescence properties of Li_6C-aLa_2Nb_2O_12:Nd^3+,Ho^3+ solid solutions in the visible, near-IR, and short-wave IR ranges under 808 nm laser diode radiation are determined. The energy transfer mechanism between active centers, involving the participation of Nd^3+ ions as sensitizers for the luminescence of Ho^3+ ions, is proposed. Low phonon energy, high luminescence intensity in the range of 2.0–3.0 μm, and weak up-conversion luminescence in the region of 450–780 nm make it possible to consider the cubic lithium–lanthanum niobates Li_6CaLa_2Nb_2O_12:Nd^3+,Ho^3+ as promising phosphors of the short-wave IR range.

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].
