Luminescence enhancement of ruthenium complexes in polymer nanosheet by surface plasmon resonance of metal nanoparticle
The luminescence properties of tris(2,2'-bipyridine) ruthenium complex (Ru(bpy)(3)(2+)) incorporated into polymer Langmuir Blodgett (LB) films (polymer nanosheets) excited by localized surface plasmon on metal nanoparticles are described. It was clearly demonstrated that the luminescence intensity of Ru(bpy)(3)(2+) was changed by the distance from the localized surface plasmon on the nanoparticle. The enhancement of luminescence by silver nanoparticle and the quenching of luminescence by gold nanoparticle were observed.
