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...
We report on the development of efficient and low cost single photon sources for quantum communications. The work discusses the suitability of colloidal nanocrystals as sources of quantum light as well as it draws out possible solutions to overtake the drawbacks of these emitters, such as blinking and polarization.
