Study of preparation and field emission properties of Bi_2O_3 nanowires
Source abstract
Abstract
Bi2O3 nanowires were synthesized from NaOH and Bi(NO3)3·5H2O with surfactants oleic acid,heptane and acetone added at room-temperature.The nanowires have a diameter of about 50nm and a length in the range of several to tens of micrometers.X-ray diffraction(XRD) analysis and scanning electron microscopy(SEM) were employed to characterize the structure and morphology of these structures.The cathode array was prepared by screen-printed.The field emission of the sample started at a turn-on field of 2.6V/μm at a current density of 0.1μA/cm2.This type of Bi2O3 nanowires can be applied as field emitters in displays as well as vacuum electric devices.
