研究了Sm（TTFA）3配合物在80 ~ 120 nm纳米银（Ag）颗粒存在下，在397 nm和350 nm两种不同激发波长（共振激发和非共振激发）下的发光性质。共振激发的发光增强远大于非共振激发。结果表明，Ag纳米粒子对电偶极跃迁和磁偶极跃迁的影响取决于发射波长与纳米粒子局域表面等离子体共振之间的重叠平衡以及对局域环境变化的敏感性。在共振激发下，观察到荧光的增强和猝灭。
The luminescence properties of Sm(TTFA)3complex in presence of the silver (Ag) nanoparticles with size ranged from 80 nm to 120 nm and different shapes (nanorod, cube, tetrahedron, and nanowire) were investigated at two different excitation wavelengths of 397 nm and 350 nm, which was resonant and off-resonant excitation, respectively. The luminescence enhancement for the resonant excitation was much greater than that for the off-resonant excitation. The electric and magnetic dipole transitions were affected by the Ag nanoparticles and the results showed that their emission enhancement depended on the balance of the overlap between the emission wavelengths and the localized surface plasmon resonant of nanoparticles and their sensibility to the variation of local environments. The enhancement and quenching of the luminescence were both observed at the resonant excitation.
