Abstract

Few reports on absorbers achieve both high transmittance of visible light and strong absorption of mid-infrared light. Here a multilayered absorber with high visible light transmittance and strong broadband absorption in the mid-infrared band is proposed. The absorber is four-layer films of ITO/SiO₂/ITO/SiO₂ successively deposited on single-sided conductive glass by electron beam evaporation technology. The experiment shows that the integral transmittance in the 400–800 nm range is 82.8 %, and the integral absorption in the 3–5 μm band is 88.2 %.

具有高可见光透过率的多层薄膜中红外宽带吸收器

有关既能实现可见光高透射率，又能实现中红外光强吸收的吸收体的报道很少。本文提出了一种具有高可见光透过率和中红外波段强宽带吸收的多层吸收体。该吸收器是利用电子束蒸发技术在单面导电玻璃上连续沉积的 ITO/SiO/ITO/SiO 四层薄膜。实验表明，400-800 nm 波段的整体透射率为 82.8%，3-5 μm 波段的整体吸收率为 88.2%。

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
