In article number 2000562, Zhengwen Yang, Bitao Liu, and co‐workers present a method of fingerprint acquisition, obtained by means of the photo‐thermal‐chromism of MoO₃ photochromism ceramic upon irradiation of multiband light outside the bandgap, which breaks the limitation of photochromism caused by monochromatic wavelength inside the band gap. The acquisition fingerprint based on the photochromism of MoO₃ ceramic exhibits excellent repeatability, high reproducibility and long preservation persistence under heat‐treatment.

指纹采集：基于带隙外多波段光照射下MoO3陶瓷的光热着色的指纹采集（Adv。Mater。Technol。11/2020）

杨正文，刘Bitao和同事在文章2000562中提出了一种指纹获取方法，该方法是通过在带隙外照射多波段光时MoO ₃光致变色陶瓷的光热致变色而获得的，从而打破了局限性。带隙内的单色波长引起的光致变色现象。基于MoO ₃陶瓷光致变色的采集指纹具有出色的可重复性，高可重复性和在热处理下的长期保存持久性。
