We fabricated whispering gallery mode (WGM) resonators by depositing a thin metal film (Ag or Al), a spacer layer (CBP), and a photoluminescent layer (Terfluorene), in that order, on a microdisk structure fabricated on a glass substrate surface using photolithography. The thickness of the metal thin film was less than 10 nm. We measured the emission spectra using this WGM resonator. In our presentation, we will discuss whether the long-range propagation mode of surface plasmons makes photoluminescence amplification effects.
