• Sm 3+ doped and RE 3+ (RE = Dy, Er, Gd, La, Nd, Tb)-co-doped CaB 6 O 10 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 CaB 6 O 10 :Sm 3+ phosphors consisted of some sharp emission peaks of Sm 3+ ions centered at 561, 601, 649, and 708 nm, generating bright orange–red light. The concentration quenching occurred when x equals 0.05 for CaB 6 O 10 :xSm 3+ phosphor. No remarkable differences were found from excitation spectra of co-doped phosphors CaB6O10:Sm 3+ , RE 3+ in contrast with that of phosphor CaB 6 O 10 :Sm 3+ . The introduction of charge compensator RE 3+ (RE = Dy, Er, Gd, La, Nd, Tb) into the host reduced the luminescence intensity of the CaB 6 O 10 :Sm 3+ phosphors.
