In this paper, hollow spherical Cu3P nanopowders were synthesized by using copper sulfate pentahydrate (CUSO4 center dot 5H(2)O) and yellow phosphorus in a mixed solvent of glycol, ethanol and water at 140-180 degrees C for 12 h. X-ray powder diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), electron diffraction pattern (ED) and transmission electronic microscopy (TEM) studies show that the as-synthesized nanocrystal is pure hexagonal phase CUR with a hollow spherical morphology. Based on the TEM observations, a possible aggregation growth mechanism was proposed for the formation Of CUR hollow structures. Meanwhile, the effects of some key factors such as solvents, reaction temperature and reaction time on the final formation of the CUR hollow structure were also discussed.
