通过一种简单的水热法，氧化锌分级结构的可控合成已成功大规模实现。研究表明，通过添加不同量的可溶性盐可简便地调控最终产物的形貌。当不添加可溶性盐时，制备出氧化锌微粒；而在不同量的氟化钠存在下，有选择性地制备出微球和纳米花。当添加适量的氯化钠、硫酸钠或硫酸钾时，得到氧化锌纳米片。在适量的柠檬酸钠（C₆H₅Na₃O₇）存在下，得到氧化锌纳米带。对这些产物的光致发光（PL）特性进行了研究，并对光致发光的起源进行了讨论。版权所有（C）2009，由爱思唯尔出版集团出版。保留所有权利。
The controlled synthesis of ZnO hierarchical structures has been successfully realized in a large scale via a simple hydrothermal method. It was demonstrated that the morphology of the final products was simply tuned by adding different amounts of soluble salt. ZnO microparticles were prepared when no soluble salt was added, whereas microspheres and nanoflowers were selectively prepared in the presence of different amounts of NaF. ZnO nanosheets were obtained when adding appropriate amount of NaCl, Na2SO4, or K2SO4. ZnO nanobelts were obtained in the presence of appropriate amount of sodium citrate (C6H5Na3O7). The photoluminescence (PL) properties of those products were researched, and the origin of the PL was discussed. Crown Copyright (C) 2009 Published by Elsevier B.V. All rights reserved.
