摘要/Abstract

摘要： 采用低温水热法在五种不同基底上制备得到了氧化锌纳米棒阵列,通过SEM、TEM、XRD、EDS和XPS表征研究了所得产物的微观形貌和元素组成,并对不同基底生长的氧化锌纳米棒阵列进行了场发射性能和附着力测试。结果表明：硅片、导电玻璃、镍片、不锈钢和镍钛合金上生长的氧化锌纳米棒样品的开启电场依次升高;由于氧化锌纳米棒与硅基底之间具有更好的附着性能,硅片基底制备的氧化锌纳米棒场发射性能最好,并显示出最好的发射稳定性,在电流密度0.5mA/cm²下持续工作15h时,其电流波动小于10%。

Abstract: Zinc oxide nanorod arrays were prepared on five different substrates using low-temperature hydrothermal method, and the microstructure and elemental composition of the products were characterized by SEM, TEM, XRD, EDS, and XPS. The field emission (FE) properties of zinc oxide nanorod arrays grown on different substrates were investigated. The results show that the turn-on fields of samples grown on Si, conductive glass, nickel, stainless steel, and nickel titanium alloy increase in turn. Attributing to the better adhesion between zinc oxide nanorods and the Si substrate, the samples grown on Si substrate have the best FE performance and the best emission stability, with a current fluctuation less than 10% under the current density of 0.5mA/cm² in DC mode for 15 h.

Key words: hydrothermal method, substrate, zinc oxide nanorod array, field emission, adhesion
