By measuring the excitation spectra of the 4f5d bands and the fluorescent decays of the 5J—70 transition probability depending on temperature in MyM′1-yFClxBr1-x:Sm2+(M=Mg,Ca,Sr,Ba)series, we have studied the dependence of the energy separation between the 4f5d bands and the 5J level, the 5J—70 transition probability on the composition grade(x) and (y) and the effect on hole-burning efficiency. We draw conclusions as below: In MyM′1-yFClxBr1-x:Sm2+ series, the 4f5d bands will be more close to the 5J level with the increase of the Br concentration and the concentration if snakk radium alkaline earth ion, and this situation makes the 5J—70 electron transition probability increase. By reasoning, the hole-burning efficiency of Sm2+ are expected to by enhanced.
