Abstract

We have fabricated a composite thin film that exhibits intense photoactivated fluorescence of silver oxide at 522 and 529nm under the irradiation of a 488nm laser. This film consists of a silver coated polymeric periodic array on indium tin oxide glass substrate. By adjusting the column diameters and lattice constants of the array to coincide with the excitation wavelength, an order increase in fluorescence intensity was obtained due to the surface plasmon polariton resonance of silver. This composite film has many potential applications in highly efficient optoelectronic devices.
