| Research Abstract |
We have demonstrated the surface plasmon excitation in the region of deep-ultraviolet (DUV) region. The fluorescence enhancement in fluorescent thin film was demonstrated by using surface plasmon excitation in DUV region. Surface plasmon resonance in deep-UV was excited on aluminum thin film in the Kretschmann-Raether geometry. Considering the oxidation thickness of aluminum, the experimentally measured incident angle dependence of reflectance show good agreement with Fresnel theory. Surface plasmon resonance was excited at the incident angle of 49 degrees for 266 nm p-polarized excitation light on the film of 18 nm-thick aluminum with 6.5 nm-thick alumina. Fluorescence of CdS quantum dots coated on this aluminum film was enhanced to 18-fold in intensity by the surface plasmon excitation.
