Abstract:
A simple solution chemical route for bulk synthesis of hand-like Bi(2)O(3) microcrystals has been demonstrated. The microcrystals are assembled by several short rods that have a diameter in the range of 50-500 nm, and a length in the range of 1-20 mu m. X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) were employed to characterize the structure and morphology of these novel structures. The field emission of the sample started at a turn-on field of 2.1 V/mu m at a current density of 0.1 mu A/cm(2), while the emission current density reached about 0.1mA/cm(2) at an applied field of 5.5 V/mu m. These results suggest that hand-like Bi(2)O(3) microcrystals can be an excellent FE material candidate.
