Nanoscale. 2015 Nov 28;7(44):18686-93. doi: 10.1039/c5nr04444h. Epub 2015 Oct 26.

Monoclinic VO2 nanoparticles are of interest due to the material's thermochromic properties, however, direct synthesis routes to VO2 nanoparticles are often inaccessible due to the high synthesis temperatures or long reaction times required. Herein, we present a two-step synthesis...
