Research Abstract |
Sol-gel derived zinc oxide-germanium oxide green-color phosphors, doped with manganese and europium ions, showed long afterglow lasting for over 3 hours. Magnesium oxide-zinc oxide-germanium oxide ceramics, doped with manganese ions, were found to be red, yellow, or green phosphors, depending on the ceramics composition. Zinc germanate transparent thin films, prepared by sol-gel method, showed high photocatalytic activity. These films doped with manganese ions emitted intense green phosphorescence. Tantalum-oxide photocatalytic thin films were also produced.
