Photoluminescence, persistent luminescence and thermoluminescence studies of Cr-doped zinc gallogermanate (ZGGO:Cr)

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...
