Abstract

Threshold reduction and emission enhancement were reported for the waveguided random lasing, assisted by the Ag-encapsulated Au nanorods (Au@Ag NRs). The blend of tris(8-hydroxyquinolinato)aluminum (Alq3) and 4-(dicyanomethylene)-2-tert-butyl-6(1,1,7,7-tetramethyljulolidyl-9-enyl)-4 H-pyran (DCJTB), which comprise the typical donor–acceptor lasing system, is used as the gain media. Compared with the Ag nanoparticles and Au nanorods, Au@Ag NRs exhibited the broad absorption spectra of localized surface plasmon resonance (LSPR) with multiple peaks, which sufficiently overlapped with both absorption and emission spectra of the donor–acceptor system of the gain media. This unique plasmonic characteristic of Au@Ag NRs leads to the lower lasing threshold and enhances the lasing efficiency by the effects of both enhancement of localized electromagnetic field and scattering.
