Abstract: In this paper, hollow spherical Cu3P nanopowders were synthesized by using copper sulfate pentahydrate (CuSO4⋅5H2O) and yellow phosphorus in a mixed solvent of glycol, ethanol and water at 140–180 ∘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 Cu3P with a hollow spherical morphology. Based on the TEM observations, a possible aggregation growth mechanism was proposed for the formation of Cu3P hollow structures. Meanwhile, the effects of some key factors such as solvents, reaction temperature and reaction time on the final formation of the Cu3P hollow structure were also discussed. [Copyright &y& Elsevier]

Abstract: Polycrystalline InP hollow nanospheres with an average size of 520nm and shell thickness of about 110nm were obtained by acid treatment of In/InP core–shell nanospheres which were solvothermally synthesized in ethanolamine–water binary solution at 180°C. The sizes of InP hollow nanospheres increased with the increasing reactants quantities. Meanwhile the shell thicknesses of InP hollow nanospheres could be controlled by varying the quantity of yellow phosphorus. The process of In/InP core–shell nanospheres transforming into InP hollow nanospheres was also investigated. The InP products prepared in our experiments can emit blue light, which is different from previous reports and increases the potential application of InP nanomaterial. [Copyright &y& Elsevier]

Coral-shaped nanocrystallites of Cu3BiS3 and AgBiS2 have been synthesized at 195°C from single-source precursors by a rapid polyol process. X-ray powder diffraction, X-ray photoelectron spectra and transmission electron microscope were used to characterize the products, which reveal that the products are phase-pure coral-shaped nanostructures. The formation mechanism is also discussed. [Copyright &y& Elsevier]
