描述了掺入聚合物 Langmuir Blodgett (LB) 薄膜（聚合物纳米片）中的三（2,2'-联吡啶）钌络合物（Ru(bpy)(3)(2+)）在金属纳米颗粒上由局域表面等离激元激发的发光特性。清楚地表明Ru(bpy)(3)(2+)的发光强度随着距纳米颗粒上局域表面等离子体的距离而变化。观察到银纳米颗粒对发光的增强和金纳米颗粒对发光的猝灭。
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.
