- Аннотация: The optical properties of aluminum hole arrays fabricated via colloidal lithography were investigated. By tuning the hole diameter and hole spacing independently, their influence on the Bloch wave–surface plasmon polariton (BW-SPP) and localized surface plasmon resonances resonances (LSPR) could be identified. The aluminum hole arrays were used to enhance the fluorescence of a dibenzoylmethanatoboron difluoride (DBMBF2) dye. The dye exhibits the advantageous property of forming an exciplex with aromatic compounds. The interaction of DBMBF2 monomer fluorescence and DBMBF2–toluene exciplexes with Al hole arrays is studied. Furthermore, the respective roles of the BW-SPPs and LSPRs were studied through tuning of the plasmon resonances from the UV excitation wavelength (λext = 385 nm) through the visible emission range (400–550 nm). Monomer emission was predominately enhanced by BW-SPPs while exciplex emission showed a contribution from both BW-SPPs and LSPRs. Fluorescence enhancement of 3.8 was observed for DBMBF2–toluene exciplex emission from 26 nm thick polymer films. Aluminum hole arrays are shown to be attractive structures for fluorescence enhancing applications with excitation in the UV and stable oxide coatings.
