Abstract

We have observed strong photoluminescence from a single CdSe quantum dot embedded in a ZnSe nanowire. Exciton, biexciton and charged exciton lines have been identified unambiguously using photon correlation spectroscopy. This technique has provided a detailed picture of the dynamics of this new system. This type of semi conducting quantum dot turns out to be a very efficient single photon source in the visible. Its particular growth technique opens new possibilities as compared to the usual self-asssembled quantum dots.
