Lasing of N,N'-bis(3-methylphenyl)-N,N'-diphenyl-[1,1':4',1”-terphenyl]-4,4”-diamine (BMT-TPD) films on silver island films (SIFs) was investigated. The size of silver nanoparticles (NPs) of SIFs ranged from 8 to 500 nm, which showed the different localized surface plasmon resonance (LSPR). It was found that the lasing wavelength of BMT-TPD was tuned by the LSPR peaks of silver NPs. This was attributed to the coupling between gain medium and plasmonic silver NPs, that is, the surface plasmon amplification by stimulated emission of radiation which resulted in the lasing at the corresponding wavelengths. This is expected to be a new and easy approach for the tuning of wavelength of lasing.
