We investigate the time-resolved photoluminescence (PL) spectra of Si-nanocrystal (Si-nc)-doped SiO 2 on Au thin films. It is shown that PL intensity within several tenth of µs after excitation is increased in the presence of Au films. The data suggest that the radiative recombination rate of excitons in Si-nc's is increased, and the degree of increase depends strongly on the emission photon energy. We show that the enhancement is caused by the modification of the local photonic mode density in the presence of Au thin films.
