In this work we propose rod-shaped core/shell CdSe/CdS colloidal nanocrystals as efficient non-classical light sources. These nanoemitters show peculiar features such as pronounced photoluminescence stability and high single-photon emission efficiency at room-temperature, making us envision their possible employment as single-photon sources for quantum communications protocols.
CdSe/CdS dot-in-rod (DR) nanocrystals, i.e. semiconductor nanoparticles consisting of a CdSe spherical core surrounded by a rod-shaped CdS shell, recently emerged as efficient sources of non-classical light for quantum cryptography applications. This paper discusses the influence of shell size on DRs quantum emission properties, showing that shell elongation has detrimental effects on DRs single photon...
Blinking and single‐photon emission can be tailored in CdSe/CdS core/shell colloidal dot‐in‐rods. By increasing the shell thickness it is possible to obtain almost non‐blinking nanocrystals, while the shell length can be used to control single‐photon emission probability.
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...
