Synthesis of nanocrystals with new composition and morphologies has attracted a lot of attention because of their wide application potentials in different devices such as photovoltaic, photoelectrochemical and photoelectronic devices. CdS1-xSex nanocrystals with different compositions and shapes are synthesized in single pot reaction of dichalcogenides with cadmium precursor using microwave assistance. The shape of resulted nanocrystals changes from spherical to simple branched and hyperbranched. Unlike core-shell nanocrystal that composition is changing hardly at the interface of the core and shell layer, here the composition of each nanocrystal varies from center to the surface gradually. The effect of reaction temperature and ratio of sulfur to selenium on the composition and shape of final nanocrystals was studied.
