Abstract

We fabricated the various nano-aperture plasmonic platforms on pyramid and on the flat membranes. The nano-apertures such as circular nanopore and nanoslit pores were fabricated. Optical characteristics were found to be dependent upon the aperture size and the sample thickness. The enhanced optical emission spectra with decreased aperture sizes have been observed due to spp-mediated emission at ~ 500 nm. In addition, the broad emission spectra in the visible and infrared region from the nanoslit array are obtained. The fabricated Au nano-aperture platform with a few nano-meter openings can be utilized as a single-molecule sensor.
