Vanadium dioxide is the key thermochromic compound for the next generation of smart windows. Monoclinic vanadium dioxide with tuned crystallinity is synthesized by a two-step thermal treatment: thermolysis of vanadyl ethylene glycolate and postannealing of the poorly crystallized VO2 powder. The proportion of crystallized VO2, calculated with the Fullprof program, increases from 44% to 79% and 100% with increasing annealing temperature up to 700 °C. Besides, V2O3 and V2O5 with particular microstructures are also successfully prepared using this method.
