Room temperature solution processing is used for cross-linked upright-standing ZnO nano-sheets growth of similar to 2-5 mu m in length and similar to 100-150 nm in width. These nano-sheets are characterized for structural and surface morphological analyses. Energy dispersive X-ray spectrum is preferred to chemical analysis. Confirmation of well defined, cross-linked and distinct ZnO nano-sheets of quoted dimensions is carried out using a scanning electron microscopy. Porous nature of nano-sheets with fine edge boundaries is noted from low resolution transmission electron microscopy. (C) 2008 Elsevier B.V. All rights reserved.
