我们报告了通过在碳纳米管（CNT）上涂覆纳米晶金刚石（NCD）制备的电子场发射体的寿命稳定性增强。在克服CNT中稳定性差的问题后，NCD-CNT在600和900 V的不同施加电压下测试时表现出250分钟的优异寿命稳定性。相比之下，CNT的寿命稳定性即使在360 V的相对低的电压下也仅为33分钟，并且在400 V下开始起弧。具有改进的寿命稳定性的NCD-CNT具有作为平板显示器和微等离子体显示装置中的阴极的应用的巨大潜力。
We report enhanced life-time stability for the electron field emitters prepared by coating nanocrystalline diamond (NCD) on carbon nanotubes (CNTs). Upon overcoming the problem of poor stability in CNTs, the NCD-CNTs exhibit excellent life-time stability of 250 min tested at different applied voltages of 600 and 900 V. In contrast, the life-time stability of CNTs is only 33 min even at relatively low voltage of 360 V and starts arcing at 400 V. Hence, the NCD-CNTs with improved life-time stability have great potential for the applications as cathodes in flat panel displays and microplasma display devices.
