In this chapter, we report the light emissionLight emission when quantum dotsQuantum dots are coupled to the surface plasmonSurface plasmons and Mie resonanceMie resonances of gold spheresGold sphere and silicon particlesSilicon particle, respectively. For gold microcavityGold microcavity, whispering-gallery-modeWhispering-gallery-mode emissionEmission of quantum dotsQuantum dots mediated by plasmonPlasmon was realized. For silicon microcavitySilicon microcavity, Mie resonanceMie resonances supressed emissionEmission blinking of quantum dotsQuantum dots was realized.
