Photothermal heterodyne imaging and spectroscopy of individual metal nanoparticles

Not Accessible

Your library or personal account may give you access

Abstract

We introduce a highly sensitive far-field optical method for imaging individual nonfluorescent nano-objects. This allows for the unprecedented detection of individual gold clusters of only 67 atoms. The spectroscopy of individual nanoclusters is demonstrated.
