摘要 针对现有的ZnO纳米针场发射均匀性、稳定性不良的问题,本文提出丝网印刷碳纳米管(CNTs)掺杂过滤的ZnO纳米针的方法来提高其均匀性和稳定性。场发射特性测试表明,ZnO纳米针经过滤后可以提高场发射均匀性,CNTs的掺杂提高了印刷ZnO纳米针薄膜的场发射电流密度和稳定性,印刷CNTs掺杂的ZnO纳米针薄膜在烧结温度为450℃时,印刷ZnO纳米针薄膜的场发射电流密度较高。该方法在ZnO纳米针场发射显示器的制作中有很好的实际应用价值。 To solve the present problem of poor uniformity and stability of field emission of ZnO nanoneedles, screen printed filtrated ZnO nanoneedles doped with CNTs were presented to improve the field emission uniformity and stability. The measurement revealed that filtration took an important role in the improvement of field emission uniformity for ZnO nanoneedles, the field emission current density and stability were improved greatly by the doped CNTs. When the sinter temperature was 450℃, the field emission current density of printed ZnO nanoneedles was higher than that of other sinter temperature. This process has a better utility value in the fabrication of ZnO nanoneedles field emission display.
