A new nonhydrolytic single-precursor approach to surfactant-capped nanocrystals of transition metal sulfides

Metal (Cd, Cu, and Ni) sulfide nanocrystals have been synthesized by a single-source molecular precursor method. The size of the nanocrystals can be well controlled by adjusting the ration of the oleylamine and precursors. This synthesis may represent a general approach towards metal sulfide nanocrystals, which may promise both adequate academic and practical interest in the development of synthetic methodologies for inorganic nanocrystals, and in the expansion of their potential applications.
