Abstract

There is a growing interest in the three-photon luminescence (3PL) of plasmonic nanoparticles. The 3PL from gold nanoparticle has been applied to deep-tissue imaging previously, but the efficiency of the process is not yet properly quantified. In this work, we look into confirming three-photon luminescence in gold nanorods at various wavelengths and measure its three-photon action cross-sections. We performed this analysis by investigating the non-linear emission from gold nanorods at 1500 nm by a custom-built scanning laser confocal microscope, as well as the bulk non-linear absorption is also measured by the z-scan technique.
