我们报道了一种使用紫精修饰的ZnO纳米线阵列作为电致变色（EC）电极的EC显示器。采用低温水热分解法在氧化铟锡（ITO）玻璃上直接生长ZnO纳米线阵列，并对其进行紫精修饰。ZnO纳米线电致变色器件显示出快速的开关时间（对于1 cm（2）电池，显色和漂白分别为170和142 ms）、高显色效率（196 C-1 cm（2））和良好的稳定性。ZnO纳米线阵列的大表面积、高结晶度和良好的电子输运性能是ZnO纳米线电致发光器件性能提高的主要原因。
We report an electrochromic (EC) display using a viologen-modified ZnO nanowire array as the EC electrode. The ZnO nanowire array was grown directly on an indium tin oxide (ITO) glass by a low temperature aqueous thermal decomposition method and then modified with viologen molecules. The ZnO nanowire electrochromic device shows fast switching time (170 and 142 ms for coloration and bleaching respectively for a 1 cm(2) cell), high coloration efficiency (196 C-1 cm(2)) and good stability. The improved performance of the ZnO nanowires EC device can be attributed to the large surface area and high crystalline and good electron transport properties of the ZnO nanowire array.
