Enhanced Förster resonance energy transfer was found for donor–acceptor pairs of cationic dyes in the presences of silver nanoparticles (NPs) in solution. This enhancement is attributed both to an increase in the fluorescence intensity of the dyes and the direct effect of local plasmon resonance of the NPs on the energy transfer rate constant. Even in the case of low energy transfer efficiency, a significant increase in the rate constant of this process in the presence of silver NPs was found to be possible.

银纳米粒子对一系列阳离子聚甲炔染料中福斯特共振能量转移的等离子效应

在溶液中存在银纳米粒子 (NP) 的情况下，阳离子染料的供体-受体对发现了增强的 Förster 共振能量转移。这种增强归因于染料荧光强度的增加和 NP 的局部等离子体共振对能量转移速率常数的直接影响。即使在能量转移效率低的情况下，发现在银 NPs 存在下该过程的速率常数显着增加是可能的。
