Cadmium selenide (CdSe) nanocrystals with wurtzite-like core and surface passivated by organic molecules have been extensively studied for the past 20 years and are already used for diverse applications, ranging from light emitting diods, to photovoltaic cells and biological markers. Recently, however, there were experimental and theoretical evidences that pointed to the existence of a novel class of CdSe nanocrystals. These are very small, magic-sized, CdSe nanoparticles with fullerene-like geometry that proved to be extremely stable. This discovery has paved the way to the development of CdSe "cluster-assembled materials" -- materials made of three dimensional ordered arrays of size-selected nanoparticles. The enormous potential of these new materials lies in the ability to fine-tune their properties by controlling the size of the constituent nanoparticles, combined with the novel collective behavior arising from the creation of nanoparticle arrays.
