Optical Microscopy of Single Nano-Objects — •Michel Orrit — Huygens Laboratory, Leiden, The Netherlands

Far-field optical microscopy and spectroscopy of individual organic molecules and other nanoparticles is relatively non-invasive, but provides first-hand insight into distributions and dynamical fluctuations at nanometer scales. The lecture will illustrate this powerful method with examples from the literature and from our group’s recent work. A particulary intriguing observation is the intermittency in the emission intensity of semiconductor nanocrystals and molecules, which follows power laws over a broad range of times. New experimental methods open an ever broadening range of timescales, from the picoseconds of electronic and acoustic relaxation in single metal particles, to days and beyond for the relaxation of dynamical inhomogeneities in supercooled liquids.
