Abstract

Novel Mn⁴⁺-doped magnetoplumbite-related aluminate X-type Ca₂Mg₂Al₂₈O₄₆ and W-type CaMg₂Al₁₆O₂₇ red phosphors were synthesized by solid-state reaction, and we investigated their photoluminescence properties. X-type Ca₂Mg₂Al₂₈O₄₆:Mn⁴⁺ and W-type CaMg₂Al₁₆O₂₇:Mn⁴⁺ exhibited red photoluminescence, with peaks at 655 and 656 nm, arising from the spin-forbidden ²E→⁴A₂ transition of Mn⁴⁺ under near-ultraviolet and blue light excitation, respectively. Therefore, these red phosphors can be excited by near ultraviolet or blue LED light. The photoluminescence properties of these phosphors were similar because magnetoplumbite-related structures crystallize similarly, forming structures consisting of stacked S and R blocks. From these results, we confirmed that magnetoplumbite-related compounds can act as the host structure for Mn⁴⁺-doped phosphors.
