蒽醌与稀土离子间的能量转移研究

分子间或分子内的电子激发态能量转移是重要的初级光化学过程，很多体系电子激发态能量转移过程已经报导1-3]，对稀土离子和谈基化合物的研究发现，用光激发配体时，激发了的配体可将能量转移给稀土离子，使稀土离子激发到发光能级，可观察到稀土的特征荧光，若稀土离子和谈基

The Study to the Energy Migration between Anthraquinone and Rare-earth Ion

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.
