Thermochromic materials such as rutile-type vanadium dioxide (VO₂) has received a lot of attention due to their potential applications in window coating to block infrared transmission and reduce the loss of building interior heat through windows as temperature increases. Other applications include optical switching devices, thermal sensors, and field-effect transistors.  These applications are based on its ability to undergo a reversible structural distortion as a function of temperature that is accompanied by a semiconductor-to-metal transition.  Here, we have prepared 1D VO₂ nanorods and observed an increased thermochromic transition temperature compared to bulk material.  Further investigations also show nanostructure variations in vanadium oxides' morphology and composition are strongly influenced by varying conditions and synthetic techniques.
