The studing results on the characteristics of the energy migratiou of excited state by fluorescent probe method are reported. The energy migration is of ligation between Eu3+,Tb3+and AQ in acetone solution.It is found that the excited state ligation is formed between AQ and Eu3+, Tb3+ in ace-tone solution. There is obvious energy migration phenomenon between ligand AQ and centre ions Eu3+, Tb3+. AQ migrates the absorbed photoenergy to Eu3+, Tb3+ and made Eu 3+, Tb3+ emit character fiuorescence, and the fluorescence intensity is increasing greatly. In addition, through studing the effect of different solvents to AQ:Eu3+ system, it is found that if the solvent polarity is different, the effect to energy migration is different. The solvent with weak polarity is benifical to electric dipole transition migration of Eu3+, and the solvent with strong ploarity is favorable magnetic dipole transition migration.
