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.
