| 英文摘要 | W18o49 nanowires were synthesized by thermal evaporation, and the effects of x-ray irradiation on their crystalline structure, chemical composition, and field emission properties were systematically investigated. high-energy x-ray irradiation created nanoprotrusions on the surface of w18o49 nanowires and introduced crystalline slipping in the lattice. x-ray photoelectron spectroscopy results showed that the content of lattice oxygen increased and nitrogen was incorporated into the w18o49 nanowires after x-ray irradiation. nevertheless, a stable and high current emission still could be obtained from the w18o49 nanowires after x-ray irradiation, with a slight increase in the threshold field from 6.4 to 7.9 mv m(-1). the mechanism of the change in crystalline structure, chemical composition, and field emission performance of w18o49 nanowires induced by x-ray irradiation is discussed. |
