Abstract

Photothermal Heterodyne Imaging (PHI) is a highly sensitive optical detection method of individual absorptive nano-objects. It can be applied to absorption spectroscopy measurements Surface Plasmon Resonance spectra of individual gold nanoparticules with diameters down to 5nm were recorded. Intrinsic size effects which result in a broadening of the Resonance are unambiguously observed and analyzed within the frame of Mie theory. Preliminary results obtained with silver nanoparticles are also presented.
