摘要：
Bi2S3 nanorods were synthesized via a simple solvothermal process in polyol media through the reaction between Bi(NO3)(3)center dot 5H(2)O, urea and CS2 at 150 degrees C for 15 h using diethylene glycol as solvent. The nanorods were characterized by XRD, TEM and SAED. The results showed that the products were well-crystallized orthorhombic phase with lattice parameters a=11.15 angstrom, b=11.3 angstrom and c=3.984 angstrom, which are consistent with the value in standard JCPDS card No. 17-0320. DEG served as an excellent solvent and structure director. Besides, compared to water and EG as solvents, the DEG system can provide a mild and homogenous condition, which is favorable to anisotropic growth and increases the yield of high quality Bi2S3 nanorods. Based on the experimental results, the growth mechanism was discussed. (c) 2006 Elsevier B.V. All rights reserved.
