Abstract

Cesium tungstate (Cs4W11O362−) nanosheets coated on an aluminum (Al) substrate turned blue in an aqueous solution, acting as an ink, and rapidly decolorized under air exposure, acting as an eraser. The decoloration rate of Cs4W11O362− nanosheets was several orders of magnitude more efficient than that of conventional tungsten trioxide (WO3) particles, owing to efficient electron transfer in the nanosheet structure.
