Abstract:
Background: Electrochromic materials can dynamically change their optical properties (such
as transmittance, absorbance, and reflectance under the action of an applied voltage, and their research
and application in the visible band have been widely concerned. In recent years, with the continuous development
of electrochromic technology, the related research has been gradually extended to the infrared
region.
Objective: This invited review aims to provide an overview of the current status of several inorganic infrared
electrochromic materials, to provide some references for future research, and to promote the research
and application of electrochromic technology in the infrared region.
Methods: This review summarizes various research results in the field of infrared electrochromic, which
includes a detailed literature review and patent search. Starting from the key performance parameters
and device structure characteristics of infrared electrochromic devices (ECDs), the research and progress
of several types of inorganic infrared electrochromic materials, including metal oxides, plasma
nanocrystals, and carbon nanomaterials, are mainly presented, and feasible optimization directions are
also discussed.
Conclusion: We believe that the potential of these materials for civilian and military applications, for example,
infrared electrochromic smart windows, infrared stealth/disguise, and thermal control of spacecraft,
can be fully exploited by optimizing the materials and their devices to improve their performance.
