摘要：
ZnO nanorods were obtained by solvothermal reaction using quantum dot precursors suspended in ethanol. The ZnO suspensions were perpared from ethanolic zine acetate solutions in the presence of lithium hydroxide, and treated by solvothermal synthesis under different reaction temperatures and duration times Parameters of processing of these nanorods were investigated including the concentration of precursors and solvothermal temperature. The ZnO nanorod powders were characterized by XRD, SEM, TEM, FT-IR, thermal analysis, and isothermal N-2(g) adsorption analyses. Commercially available ZnO nanopowders were studied for comparison. Resulting ZnO nanored powders were pure ZnO and showed higher surfaces area than commercial ZnO nanopowders. Length and diameter of ZnO nanorods depended on the concentration of precursors and the annealing temperature employed. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
