Abstract

Abstract: Belt-like X-doped VO2(M) (X=W, Mo, Sn or Fe) with rectangular cross sections were successfully synthesized by a facile one-pot hydrothermal approach. The as-obtained samples were characterized by XRD, XPS, SEM, DSC and variable-temperature IR. The results showed that the additives W, Mo, Sn and Fe could promote the formation of VO2(M) under hydrothermal conditions. The additives had little influence on the morphology of doped VO2(M), but they were the key factor for the synthesis of VO2(M). The W and Mo atoms could effectively reduce the T c of VO2(M), while Sn and Fe atoms had little influence on T c. Furthermore, it was found that the as-obtained doped VO2(M) possessed prominent thermochromic properties and optical switching characters. [Copyright &y& Elsevier]
