VO2(M) with narrow hysteresis width from a new metastable phase of crystallized VO2(M)·0.25H2O

VO2(M) nanomaterials with narrow hysteresis width of 3.4 °C has been prepared by dehydration of a novel phase of crystallized VO2(M)·0.25H2O. The structure and composition have been investigated, and the dehydration process has been analyzed combining the thermal analysis of TGA and DSC. It provides a new way to obtain efficient VO2(M) that will be beneficial for high sensitive electrical/optical devices or other applications.
