This paper reports a comprehensive study of single-phase polycrystalline chromium-doped zinc gallogermanate (ZGGO:Cr) synthesised by high-temperature solid-state reaction, employing photoluminescence (PL), persistent luminescence (PersL) and thermoluminescence (TL) measurements. A bandgap...
Zn1+xGa2−2xGexO4 (ZGGO:Cr)-persistent phosphor, with a molar fraction, x, of x = 0.1, doped 0.5% chromium, was synthesised via solid-state reaction at 1350 °C for 36 h. X-ray diffraction measurements and Raman spectroscopy evidence single crystalline phase corresponding to the cubic spinel structure. Room temperature (RT) photoluminescence (PL) afterglow decay profiles were investigated using above below bandgap excitation. In both cases, persistent PL observed almost 8 h, mainly originating...
