Colloidal nanocrystals are widely used in various applications such catalysts, electronic devices, phosphors, and magnetics. Among them, highly uniform metal nanocrystals, for example gold, silver, and copper, have been intensively studied due to unique optical and electronic properties varied with their size, shape, and compositions. Here, we present high temperature thermal decomposition reaction to synthesize highly uniform copper nanocrystals with precise control of their size and shape. By changing the reaction parameters, we are able to synthesize the copper nanocrystals in different shapes such as nanospheres, nanowires, nanotriangles, and nanocubes. Properties of copper nanocrystals are characterized from solution processed thin-films to understand their size and shape dependent physical properties |
