| مستخلص: |
Large-scale well-aligned ZnO nanotubes with outer diameters of 100–300 nm and lengths oftens of micrometres have been prepared by a template-based chemical vapour depositionmethod. The photoluminescence spectrum of the ZnO nanotube arrays consists of a strongviolet band at 414 nm, a blue band at 462 nm and a weak shoulder peak at around 480 nm.The field emission of the ZnO nanotube arrays shows a turn-on field of about7.3 V µm−1 at a current densityof 0.1 µA cm−2 and emissioncurrent density up to 1.3 mA cm−2 at a bias field of 11.8 V µm−1.
