中文摘要	cubic monodisperse bacef5 and bacef5:tb3+ nanocrystals have been successfully synthesized by a citric acid assisted solvothermal method. the crystalline phase, size, morphology, and luminescence properties were characterized using powder x-ray diffraction (xrd), field emission-scanning electron microscopy (fe-sem), transmission electron microscopy (tem), photoluminescence (pl), photoluminescent excitation spectra (ple) as well as dynamics decay. the results reveal that the tb3+-doped bacef5 sample shows a strong green emission centered at 546 nm, corresponding to the d-5(4)-> f-7(5) transition of tb3+ due to an efficient energy transfer from ce3+ to tb3+. the decay lifetime of ce3+ monotonically increases with increase of tb3+ concentration. the critical energy transfer distance between ce3+ and tb3+ was also calculated by methods of concentration quenching and spectral overlapping. experimental analysis and theoretical calculations reveal that the dipole-dipole interaction should be the dominant mechanism for the ce3+-tb3+ energy transfer.
