摘　　要：光子晶体(Photonic crystals,PCs)是一种周期性排列有序的微结构材料,由于具有独特的周期结构、灵活的光调控能力等特点被广泛应用于电致变色(Electrochromicsm,EC)领域。具有光子晶体结构的电致变色器件可利用其产生的结构色与电致变色的化学色相结合,进而丰富和拓展器件的色域,为电致变色的色彩调控提供新的策略。此外,多维光子晶体结构可以为电致变色器件(Electrochromic devices,ECDs)提供有序离子传输通道和多离子活性反应位点,促进离子的注入/脱出,从而提升器件的电致变色性能。本文扼要介绍了评价电致变色材料与器件性能的参数,着重归纳了不同维度光子晶体在电致变色领域的应用策略,并详细总结了具有光子晶体结构的电致变色器件在智能窗、显示、伪装等领域的潜在应用。最后,针对目前光子晶体结构在电致变色领域中仍存在的问题,对其未来的发展趋势进行了展望。Photonic crystals(PCs)are artificially ordered microstructure materials.In recent years,photonic crystals have been gradually used in the electrochromism(EC)field because of unique characteristics,such as continuous periodic structures,and the ability of light regulation.Electrochromism devices(ECDs)with photonic crystal structures can enrich the color gamut by combining photonic band gaps with electrochromism,which provides a novel way to adjust electrochromism color.In addition,multidimensional photonic crystals can provide ordered ion transport channels and rich ion-active reaction sites for electrochromic devices,thus promoting ion insertion/extraction and improving electrochromism performance.Herein,this paper firstly clarfies the performance parameters to evaluate electrochromism materials and devices and the manufacturing strategies of different dimensional photonic crystals in the electrochromism field.It summarized in detail the applications of electrochromism materials and devices with photonic crystal structures including smart windows,displays,and camouflage.It ends with a discussion on the limitations and prospects of photonic crystals in the field of electrochromism,and regarding problems existing in their development.
