Novel efficient deep-red emitting phosphor SrCa₂Ga₂O₆:Mn⁴⁺ with tululite-related structure.

ABSTRACT: Mn⁴⁺-activated phosphors have been attracted to replace the rare-earth-activated phosphors in the use of deep-red optical devices. Owing to their low toxicity and wide applications, oxide materials are promising hosts for Mn⁴⁺ phosphors. Exploration into novel oxides is important for developing new Mn⁴⁺-doped phosphors with high luminescent efficiencies. In this study, we discovered the deep-red emitting phosphor SrCa₂Ga₂O₆:Mn⁴⁺ in the Sr₃Ga₂O₆-Ca₃Ga₂O₆ solid solution system. From the single crystal X-ray diffraction analysis, SrCa₂Ga₂O₆:Mn⁴⁺ was found to crystallize in a cubic unit cell with space group <
