The fabrication of conical nanocarbon structures (CNCSs) on a transparent and flexible nafion substrate at room temperature using an ion irradiation technique and their application toward field emission displays (FEDs) have been demonstrated. The main advantage of this technique is that CNCSs can be fabricated directly on the transparent substrate while retaining the transparency of the substrate. A scanning electron microscopy (SEM) image revealed that the sputtered surface was entirely covered with CNCSs with a calculated numerical density of 6 x 10(6) /mm(2). Such nafion based CNCSs have proved to be an effective electron emitter with turn-on and threshold fields of 6.1 and 9.5 V/mum, respectively. The field enhancement factor was estimated to be 1020 from the Fowler-Nordheim (F-N) plot. Thus the room temperature fabricated CNCSs based on transparent and flexible nafion substrate would be very promising for future flexible (roll-up) and transparent FEDs.
在室温下使用离子辐照技术在透明且柔韧的全氟磺酸膜（nafion）基底上制造锥形纳米碳结构（CNCSs），并将其应用于场发射显示器（FEDs），这已经得到了证明。该技术的主要优势在于，CNCSs 可以直接在透明基底上制造，同时保持基底的透明性。扫描电子显微镜（SEM）图像显示，溅射表面完全覆盖有 CNCSs，其计算得到的数值密度为 6 x 10(6) /mm(2)。基于全氟磺酸膜的这种 CNCSs 已被证明是一种有效的电子发射器，其开启电场和阈值电场分别为 6.1 和 9.5 V/mum。从 Fowler-Nordheim（F-N）图中估算出的场增强因子约为 1020。因此，基于透明且柔韧的全氟磺酸膜的室温制造的 CNCSs 有望成为未来灵活（可卷起）和透明 FEDs 的理想选择。
