Silver nanoplates (AgNP) are triangular–shaped silver nanoparticles which show intense surface plasmon bands in visible and neared infrared regions. This AgNP is expected to generate strong localized optical-electric field and contributed each plasmonic phenomena. In this work, we studied two-photon excited fluorescence (TPF) enhanced by the localized optical-electric field. We investigated the relationship between TPF intensities and aggregation of AgNPs on a substrate.
