Spectral properties and electromagnetic field enhancement effects on nano-engineered metallic nanoparticles

Plasmonic chemistry, a new research field dedicated to understanding plasmon-enhanced photochemical reactions, has become a principal area of chemical research, especially in the field of physical chemistry. In this perspective review article, we describe our recent research regarding the development of a fabrication methodology for metallic nanostructures that exhibit localized surface plasmon resonance, the spectral properties of the fabricated metallic nanostructures and their electromagnetic field enhancement effects using two-photon-induced photoluminescence from gold nanoparticles.
