Abstract
We present the enhancement of fl uorescence excitation with deep-UV surface plasmon resonance (DUVSPR). We selected aluminum as the material to excite DUV-SPR because it has negative permittivity and a small imaginary part in the DUV region. We demonstrated DUV-SPR excitation on aluminum fi lm with a Kretschmann confi guration, and presented the fl uorescence enhancement of quantum dots (CdSe) with DUV-SPR excitation. We increased the enhancement of fl uorescence intensity by DUVSPR. We expect that DUV-SPR will be applied for the observation of the autofl uorescence of biological samples with high sensitivity.
