The photoluminescence eigenmodes of the ZnO semiconductor microcavity on a Ag/Si substrate at room temperature. The photoluminescence modes do not depend on the excitation intensity. The eigenmode in the microcavity is considered to be the perpendicular Fabry-Perot modes, where the effect of the strong coupling between plasmon and exciton is observed with the reducing of the effective refractive index from original 2.0 to 1.67 at the wavelength of 585 nm. Meanwhile, there is also a coupling between the plasmon and the exciton-polariton in the band-edge region, and the effective refractive index 1.92 is in good agreement between the experimental and the theoretical results.
