| 摘 要： | Energy transfer in LaOBr:Tb_(0.0075),Gd_x(x<0.30)was investigated via excitation spectra,emissionspectra,fluorescence decay function and X-ray diffraction.Effective energy transfer from Gd to Tb was found.With excitation of λ=275nm,no Gd~(3+)but only Tb~(3+)emission has been observed,and the integrated intensityof Tb~(3+)emission increases with increasing Gd content up to～5.5 times(in the sample of x=0.30)compared tothat of the sample without Gd.The existense of Gd in the sample slows down the Tb~(3+)flourescence decay,andmost likely the electric dipole-dipole interaction dominates the energy transfer process.
