Thermochromic VO{sub 2} nanorods were prepared via thermal conversion of the metastable VO{sub 2}-B phase synthesized by hydrothermal methods. We observe an increased thermochromic transition temperature to {approx}75-80 deg. C by variable-temperature infrared spectroscopy. Nano- and sub-micron structures of other vanadium oxides (V{sub 3}O{sub 7} (NH{sub 4}){sub 0.5}V{sub 2}O{sub 5}, and V{sub 2}O{sub 5}) were obtained simply by varying the starting materials in the hydrothermal synthesis. We also obtained nanostructures of the high temperature tetragonal rutile phase of VO{sub 2} by thermolysis of single-source vanadium (IV) precursors.
