Scattering imaging of single quantum dots with dark-field microscopy.
Scattering images of single quantum dots (QDs) are obtained with a standard dark-field microscope at a video rate. The counts of QDs under dark-field remained constant while the scattering intensity decreased, providing direct proof of quantum dot photophysical bleaching as opposed to desorption or photodecomposition.
