Abstract

The luminescence properties of Sm(TTFA)3 complex 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. © Springer Science+Business Media B.V. 2011.
