Uniform Bi(2)S(3) whiskers were synthesized via a template-free hydrothermal route using bismuth nitrate (Bi(NO(3))(3).5H(2)O), thiourea (CS(NH(2))(2)), and lithium hydroxide (LiOH) as starting materials. The resultant powders were characterized in detail by X-ray diffraction, scanning electron microscopy, and photoluminescent spectra techniques (PL), respectively. It was found that Bi(2)S(3) whiskers could be easily synthesized in the presence of LiOH, whereas only irregular and aggregated particles were obtained without adding LiOH, and that elevating hydrothermal reaction temperature in a certain range would promote the preferred orientation growth of Bi(2)S(3) crystallites. The PL spectra results evidenced that the optical properties of Bi(2)S(3) crystallites were obviously influenced by their size and morphology.
