Abstract

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 emission effectiveness.
