We have developed synthesis protocols of core/shell semiconductors nanocrystals in CdSe/CdS and CdSe/CdS/ZnS. The perfectly crystalline shell improve the fluorescence properties of the nanocrystals as well as their resistance to environment modifications. We have shown that the crystal structure can be choose and controlled during synthesis by a judicious choice of the surface ligands. Moreover, we show that the fluorescence blinking of such nanocrystals can be strongly reduced or even suppressed if we synthesize core/shell CdSe/CdS nanocrystals with a sufficiently thick CdS shell. These objects are studied in single particle experiments. Fluorescence and lifetime measurements allow us to identify the blinking reduction mechanism. The natur...
