Thermometry of plasmonic nanostructures by anti-S tokes electronic Raman scattering

Research output: Contribution to journalArticle

Abstract

Measurements of temperature of optically excited plasmonic nanostructures are needed to evaluate their functionality and thermal stability. Here, we describe a simple, accurate, and non-invasive thermometry based on anti-Stokes electronic Raman scattering. We validate the approach using an array of uniformly heated Au nanodisks and perform experiments on the heating of individual nanodisk by a focused laser beam. The steady-state temperature rise of an individual nanodisk has comparable contributions from the thermal conductance of the Au/quartz interface and heat spreading in the quartz substrate. The temperature measurements have an accuracy of 3% of the absolute temperature in the range of temperatures 300 < T < 700 K.
