Creation of advanced optical responsive functionality of ceramics by green processes

Abstract

Various kinds of optical responsive ceramic nanomaterials and films were successfully synthesized by environmental friendly green processes, such as hydrothermal/solvothermal process, mechanochemical doping process, oxygen plasma treatment process and a water molecular controlled-release solvothermal process (WCRSP). The composites combined the high-sensitive anion doped photocatalysts with up-conversion or long afterglow phosphors showed excellent deNOx photocatalytic activity under UV/ visible/NIR light irradiation, or even after turning off light irradiation. The mixed valence state tungsten based homogeneous nanomaterials possessed excellent IR light responsive properties, implied their potential applications as smart window materials and photothermal ablation cancer therapy materials. Significant contributions are expected for the development of optical responsive functional materials by green processes.
