Abstract

High-quality core/shell CdSe/CdS colloidal nanocrystals are demonstrated to be efficient sources of non-classical light. As shown by Ferruccio Pisanello and co-workers on page 1974, the intrinsic anisotropy of these nanoparticles allows an independent tuning of shell length and thickness, resulting in a full control of photon statistics. This can be exploited to obtain non-blinking, room-temperature single-photon generation, thus bringing colloidal nanocrystals one step closer to non-classical light sources for quantum applications.
