Complete B-site cation regulation accomplish UV-excited red phosphors in double perovskite oxides

Insights into luminescence thermal quenching of Mn4+-doped BaLa(Na/Li)(W/Te)O6 double perovskite red phosphors

“…Such a structure suggests the possibility for substitution of cations and distortion of the octahedra that makes double perovskites flexible for doping with luminescent ions including transition metals. 18,19 It has been reported that the substitution of Ca/Sr/Ba cations allows the improvement of the luminescence thermal stability of ALaLiWO 6 20 and ALaLiTeO 6 . 21 The main luminescence properties of Mn 4+ doped BaLaLiTeO 6 and BaLaLiWO 6 were earlier reported to be have prospects for plant cultivation technologies.…”
