Abstract
Localized surface plasmon excitations in metallic nanoparticles with either absorbing or amplifying media are analyzed. In the case of absorption, we present the first direct measurements of enhanced absorption in two dimensional films of dyes and isolated metallic nanoparticles. These results are of particular importance for enhancing the performance of low cost solar cells by allowing for a reduction in the thickness of amorphous layers that have poor conduction properties. Materials specific to the application of plasmon enhancement of TiO2 dye sensitized solar cells are also described. The situation where the surrounding medium is capable of amplification is studied and the required gains for real metals are determined. In addition, the enhancement of local fields in such systems is estimated and discussed in terms of further enhancing Surface Enhanced Raman Spectroscopy processes for molecular detection.
