Abstract
- Abstract: Large-scale copper sulfide polycrystalline nanorods have been solvothermally synthesized through a Cu(acac)2 precursor decomposition and reaction route. X-ray diffraction (XRD) showed that the product was hexagonal phase CuS with lattice constants of a =3.795Å and c =16.42Å. Field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) investigated the morphology of the product under the different growth conditions. PL spectra indicated that the rod-shaped product had emission peaks at 414 and 437.5nm when the excitation wavelength was 371.5nm, but the CuS dendrite did not demonstrate emission peaks at the same condition. A mechanism of Cu(acac)2 micronrods decomposition and reaction with CS2 in situ was suggested based on the TEM observation. [Copyright &y& Elsevier]
