具有功能化石墨烯电极的均匀明亮、柔性和可折叠的照明设备
Homogeneously bright, flexible and foldable lighting devices with functionalised graphene electrodes
摘要：
交流电致发光技术允许制造大面积、平面和柔性的灯。目前，连续面板的最大尺寸受到可获得的透明电极材料的高电阻率的限制，导致可见的亮度梯度。在这里，我们证明了使用最知名的透明导体FeCl $_{3}$插层的少层石墨烯与原始石墨烯相比将电致发光器件的亮度提高了49 $\%$。当使用这些高导电电极时，对于高纵横比装置观察到的强度梯度是不可检测的。聚合物基板上的平面灯被发现是有弹性的重复和弯曲应变。
英文摘要：
Alternating current electroluminescent technology allows the fabrication of large area, flat and flexible lights. Presently the maximum size of a continuous panel is limited by the high resistivity of available transparent electrode materials causing a visible gradient of brightness. Here, we demonstrate that the use of the best known transparent conductor FeCl$_{3}$-intercalated few-layer graphene boosts the brightness of electroluminescent devices by 49$\%$ compared to pristine graphene. Intensity gradients observed for high aspect ratio devices are undetectable when using these highly conductive electrodes. Flat lights on polymer substrates are found to be resilient to repeated and flexural strains.
