Precise topographic manipulation in polyoxometalate/polymer enables multi-level optical authentication.
Surface topographic manipulation plays a key role in advanced photonic devices. However, traditional azobenzene polymers or photoresists still face significant challenges in response speed and processing precision. Herein, we couple ultra-small polyoxometalate molecules with polyvinyl alcohol through hydrogen bonding t...
