摘要：
A novel three-dimensional (3D) prickly-like SnO2 nanostructure has been effectively synthesized by a hydrothermal method. The obtained nanostructures consist of SnO2 nanosheets and arrayed SnO2 nanorods. The field-emission properties of prickly-like SnO2 nanostructures have been measured to exhibit a lower turn-on electric field of 0.87 V mu m(-1), threshold electric field of 1.2 V mu m(-1). This high-performance emitter material can be applied as field-emission flat panel displays and cold electron sources in display devices. (C) 2014 Elsevier Ltd. All rights reserved.
