Abstract:
Controlled synthesis of hyperbranched CdTe and CdSe semiconductor nanocrystals is presented. The length of the arms and the degree of branching could be controlled independently by varying the amount and kind of organic surfactant. The three-dimensional structure of these nanocrystals has been characterized with TEM tomography.
