Low polydispersity core/shell nanocrystals of CdSe/ZnSe and CdSe/ZnSe/ZnS type: preparation and optical studies

A new method for the preparation of core/shell semiconductor nanocrystals of the A(II)B(VI) family is described, which involves the use of safe and cheap reagents at each synthesis stage, namely cadmium oxide as the Cd source and zinc stearate as the Zn source. It enables the fabrication of highly l...

Zusammenfassung:	A new method for the preparation of core/shell semiconductor nanocrystals of the A(II)B(VI) family is described, which involves the use of safe and cheap reagents at each synthesis stage, namely cadmium oxide as the Cd source and zinc stearate as the Zn source. It enables the fabrication of highly luminescent CdSe/ZnSe core/shell nanocrystals exhibiting a polydispersity
