摘要: 稀土有机络合物是一类重要的发光物质,它在生物化学等领域已得到广泛应用。络合物中有机配位体的单重态S1吸收的光能可能通过三重态T1传递到稀土离子,使稀土离子内壳层4f电子受到激发,进而发出稀土离子的特征荧光。

Abstract: The kinetics of luminescence and energy transfer in Eu(TTA) and Eu(DB)3in organic solutions with time-resolved spectrum is reported. Theresults show that the energy absorbed by the organic ligands transfers to the 5D1level of Eu3+, then the 5D0level and is populated by nonradiativeenergy transfer from the 5D1level.

Key words: Energy transfer, Kinetics of luminescence, Time-resolved spectrum
