Three novel kinds of hierarchical ZnO nanostructures: nanocombs nanoscrewdrivers and nanonails, have been synthesized in large quantities via a simple thermal evaporation process in the same run of growth in different regions of the quartz tube. The morphologies could be well controlled by adjusting the distances between the source materials and the substrates. These ZnO products were investigated by scanning electron microscopy, X-ray diffraction and Raman spectroscopy. The field emission properties of the ZnO nanostructures were investigated. These hierarchical ZnO nanostructures may be attractive building blocks for field emission microelectronic devices and other devices.

A simple hydrothermal route was employed to prepare flower-like SnS2 and In -doped SnS2 by using biomolecular L-cysteine as sulfur source. The synthetic samples were characterized by X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy, X-ray photoelectron spectroscopy and Raman spectroscopy in detail. Furthermore, the field emission from both the materials was investigated, it was found that both of them have excellent field emission properties, and the doped In has enhanced the field emission properties.

Prepared Nanorods

A new nanostructure, 1D In2O3nanorod, have been grown on single silicon substrates by Au catalyst assisted thermal evaporation of In2O3and active carbon powders. The morphology and structure of the prepared nanorods are determined on the basis of field-emission scanning electron microscopy (FESEM) and x-ray diffraction (XRD). The field-emission properities of In2O3nanorods have been measured and analysed. The growth mechanism of the In2O3nanorods can be explained on the basis of the vapor–liquid–solid (VLS) processes.

Cu Substrates

In the present work, ZnO nanostructures with tunable size were successfully synthesized on non-seeded Cu substrates by a simple electrodeposition method. The effects of growth conditions on the morphology of the products were studied in detail by scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The as-prepared products exhibited flake-like morphology when the concentration of ZnCl2 was higher enough, while the products showed flower-like morphology when the concentration was lower enough. Field emission investigation indicated that the nanoflowers exhibited good emission properties. The ZnO nanoflowers show potential application as field emitters.
