Bi 2 S 3 hierarchical columniform structures assembled by nanothorns have been first synthesized by a hydrothermal method through the reaction between bismuth(III) monosalicylate [BiO(C 7 H 5 O 3 )] as the precursor and sodium thiosulfate in H 2 O at 180 °C without any surfactants. These new Bi 2 S 3 structures were characterized by X‐ray diffraction, scanning electron microscopy, ultraviolet–visible spectroscopy, photoluminescence spectroscopy, Fourier transform infrared spectra, X‐ray photoelectron spectroscopy, and energy‐dispersive x‐ray microanalysis. The influences of the synthetic parameters were discussed, and a possible growth mechanism for the formation of these complex structures was proposed. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
