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.

溶胶-凝胶衍生的氧化锌-氧化锗绿色荧光粉，掺杂锰和铕离子，显示出持续超过 3 小时的长余辉。掺杂锰离子的氧化镁-氧化锌-氧化锗陶瓷被发现是红色、黄色或绿色磷光体，具体取决于陶瓷成分。采用溶胶-凝胶法制备的锗酸锌透明薄膜表现出较高的光催化活性。这些掺杂锰离子的薄膜发出强烈的绿色磷光。还生产了氧化钽光催化薄膜。
