The development of efficient nanoscale photon absorbers, such as plasmonic or high-index dielectric nanostructures, allows the remotely controlled release heat on using light. These photothermal nanomaterials have found applications in various research and technological fields, ranging from materials science to biology. However, measuring thermal fields remains an open challenge, hindering full comprehension control phenomena. Here, we review discuss existent thermometries suitable for single nanoparticles heated under illumination. methods are classified four categories according region where they assess temperature: (1) average temperature within a diffraction-limited volume, (2) at immediate vicinity nanoparticle surface, (3) itself, (4) map around with spatial resolution. In latter, because it is most challenging informative type method, also envisage new combinations technologies that could be helpful retrieving maps. Finally, analyze provide examples strategies validate results obtained different thermometry methods.
