Temperature measurement of nanoparticles (NPs) under heating is an important technique in order to achieve potential applications such as photothermal cancer therapy and nanofabrication. We implemented the method to estimate the local temperature of a laser-heated gold NP on glass substrate in various surrounding media by applying the light scattering spectroscopy. We discuss experimental results in comparison with the calculation by COMSOL Multiphysics. We found that the contact area of NP/substrate and co-adsorbed water layer on the substrate is crucial to the computational outcome.
