Abstract

In contrast to conventional lasers, random lasers (RLs), without cavity mirrors, were generated based on recurrent light scattering within nano-materials and possessed peculiar properties for practical applications. Todate, resarchers are not only interested in the novel nano-materails for the generation of RL but also curious in the manipulated property of RL through temperature and electric filed [1]. In addtion, plasmonic random laser (PRL)[2] based on the localized surface plasmon resonance (LSPR) of metallic nanoparticles has attracted great interest. In this work, the dye-covered PVA (DC-PVA) film with the embedding of silver nano-particles (AgNPs) was produced to investigate the enahcment of emission spike intensity from PRL and the underlying mechanim by varying the size and shape of AgNPs.
