Multishell semiconductor nanocrystals

  • Chapter
Semiconductor Nanocrystal Quantum Dots

Abstract

Nanocrystals consisting of more than one material are a topic of special interest almost since the beginning of the wet chemical synthesis of these materials. Socalled core shell nanocrystals were synthesized, e.g. from water-based CdS nanocrystals to improve their emission quantum yield significantly [1]. Nowadays, quite a number of different and even better defined core shell particles can be synthesized also in high-boiling organic solvents. Well known examples are, e.g. CdSe/ZnS [2] and CdSe/CdS [3].
