Quantum dots

Artificial atoms for quantum optics

Nature Materials volume 5, pages 855–856 (2006)Cite this article

Colloidal quantum dots are efficient nanoscopic light emitters with interesting applications from optoelectronics to biomedical imaging. Their polarizability has now been measured directly by probing the electronic response without electrical contacts.
