Abstract
We present a new implementation of anti-Stokes thermometry that enables the in situ photothermal characterization of individual plasmonic nanoparticles from a single hyperspectral photoluminescence confocal image. We study the photothermal response at the single-particle level of spherical gold NPs with sizes ranging from 50 to 100 nm supported on glass, sapphire and graphene substrates. In addition, we study bimetallic Au@Pd NPs in a core@shell configuration. The developed method allows quantitative assessment of the role of temperature in plasmon-assisted applications.
