Совместно легированные ионами Sm3+ и RE3+ (RE = Dy, Er, Gd, La, Nd, Tb) люминофоры CaB6O10 получены при 800°C методом твердофазной реакции. Полученные порошки структурно охарактеризованы методами рентгеноструктурного анализа и ИК-Фурье-спектроскопии. Спектры излучения люминофоров CaB6O10:Sm3+ состояли из нескольких пиков излучения ионов Sm3+ с центрами 561, 601, 649, 708 нм, генерирующих яркий оранжево-красный свет. Концентрационное тушение происходило при x = 0.05 для люминофора CaB6O10:xSm3+. Отличий спектров возбуждения легированных люминофоров CaB6O10:Sm3+, RE3+ от спектров возбуждения люминофора CaB6O10:Sm3+ не обнаружено. Введение в матрицу компенсатора заряда RE3+ (RE = Dy, Er, Gd, La, Nd, Tb) снижает интенсивность люминесценции люминофоров CaB6O10:Sm3+.

Sm3+ doped and RE3+ (RE = Dy, Er, Gd, La, Nd, Tb) co-doped CaB6O10 phosphors were prepared at 800°C by the solid-state reaction method. The obtained powders were structurally characterized by X-ray diffraction and Fourier transform infrared analyses. The influences of co-doping rare earth ions on their luminescent properties were also investigated. The emission spectra of the CaB6O10:Sm3+ phosphors consisted of some sharp emission peaks of Sm3+ ions centered at 561, 601, 649, and 708 nm, generating bright orange-red light. The concentration quenching occurred when x equals 0.05 for CaB6O10:xSm3+ phosphor. No remarkable differences were found from excitation spectra of co-doped phosphors CaB6O10:Sm3+, RE3+ in contrast with that of phosphor CaB6O10:Sm3+. The introduction of charge compensator RE3+ (RE = Dy, Er, Gd, La, Nd, Tb) into the host reduced the luminescence intensity of the CaB6O10:Sm3+ phosphors.
