Abstract
We examined the excitation wavelength dependence of photoluminescence PL property in CdSe/CdZnS colloidal quantum dots QDs on micropatterned silver Ag films MPSFs PL quenching of the fluorophore was observed when the excitation wavelength was out of the absorption range of MPSF substrates In contrast when the excitation wavelength was within the absorption spectrum range the PL intensity on Ag films was markedly enhanced by a factor of two It was expected that the principal causes on the PL properties of the fluorophore on Ag films would be the energy match between the incident light and the surface plasmon of Ag metal films
