制备了基于双核钌配合物和多晶氧化钨的近红外电致变色衰减器，并对其进行了表征。结果表明，采用nir吸收钌配合物作为对电极材料可以提高器件的性能。用nir吸收钌配合物取代可见电致变色二茂铁后，1550 nm处的光衰减从19.1 dB提高到30.0 dB，显色效率从29.2 cm2/C提高到121.2 cm2/C。
A near infrared (NIR) electrochromic attenuator based on a dinuclear ruthenium complex and polycrystalline tungsten oxide was fabricated and characterized. The results show that the use of the NIR-absorbing ruthenium complex as a counter electrode material can improve the device performance. By replacing the visible electrochromic ferrocene with the NIR-absorbing ruthenium complex, the optical attenuation at 1550 nm was enhanced from 19.1 to 30.0 dB and color efficiency also increased from 29.2 to 121.2 cm2/C.
