摘要

CdSe/CdS点在棒纳米晶体(DR)，即半导体纳米粒子组成的CdSe球形核心包围着一个棒状的CdS壳，最近出现的非经典光源的量子密码学应用。本文讨论了壳尺寸对DRs量子发射性能的影响，表明壳伸长对DRs单光子发射效能有不利影响。

Effect of shell size on single photon emission performances of core/shell dot-in-rods colloidal nanocrystals

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.
