Abstract Tungsten oxide is an electrochromic material, from which thin films are conventionally fabricated via heat treatment. Here, we develop a flash light sintering method to reduce sintering time; sintering delivers instantaneous photon energy created via the photothermal effect. The electrochromic efficiency of device with a flash light-sintered electrode was 88.50 cm2/C, about 1.46-fold greater than that of the device with a heat-sintered electrode. The diffusion coefficients of the former device were 1.35- and 1.46-fold greater than those of the latter device during bleaching and coloring, respectively. Therefore, a new way of sintering electrode was studied to show that the device with flash light–sintered electrode demonstrate better electrochromic performance than the device with heat-sintered one by enabling amorphous phase formation.

溶胶-凝胶基WO3电极不同烧结方法电致变色器件电致变色特性比较

摘要 氧化钨是一种电致变色材料，通常通过热处理来制造薄膜。在这里，我们开发了一种闪光灯烧结方法，以减少烧结时间；烧结提供通过光热效应产生的瞬时光子能量。带有闪光烧结电极的器件的电致变色效率为 88.50 cm2/C，比带有热烧结电极的器件的电致变色效率高约 1.46 倍。在漂白和着色过程中，前一种装置的扩散系数分别比后一种装置的扩散系数大 1.35 倍和 1.46 倍。因此，研究了一种新的烧结电极方式，以证明具有闪光烧结电极的器件通过使非晶相形成，比具有热烧结电极的器件表现出更好的电致变色性能。
