Abstract
In this work, we performed the photoluminescence and plasmon resonance of nanoparticle films. Using the extinction spectra as the basis of signals of plasmon resonance, and we compare the extinction and PL spectra. In the experiment we measure on three kind of nanoparticle films, close-pack gold nanoparticle films change the size and numbers of layer and deposited by using E-beam evaporator. We systematically observed simultaneous red shift in PL and extinction spectra with increasing particle size and confirm that L-mode resonance also contributed to the PL of the multilayer close-pack gold nanoparticle films. For Au nanoparticle film deposited by using E-beam evaporator, we observed blue shift of the photoluminescence peak (relative to the scattering peak).
