Abstract
A novel aluminosilicate red phosphor Sr3Al10SiO20:Mn4+, which has some octahedral sites, was synthesized by a solid-state reaction, and we investigated its photoluminescence properties. Sr3Al10SiO20 doped with tetravalent manganese showed a red photoluminescence transition from 2E to 4A2 after excitation in the near ultraviolet region to the blue region in the visible spectrum. The Sr3Al10SiO20:Mn4+ synthesized at 1500 °C for 6 h exhibited maximum emission intensity. From these results, it was confirmed that aluminosilicates could be the host structure for Mn4+-doped phosphors.
