Fluorine-doped VOsub>2</sub>(M) nanoparticles have been successfully synthesized using the hydrothermal method at a supercritical temperature of 490°C. The pristine VO<sub>2</sub>(M) has the critical phase transformation temperature of 64°C. The morphology and homogeneity of the monoclinic structure VO<sub>2</sub>(M) were adopted by the fluorine-doped system. The crystallinity and particle size were reduced the bigger the concentration of fluorine doping. The obtained particle size of the samples is smaller at the higher concentration of anion doping. The best reduction of critical temperature was achieved by fluorine doping of 0.13% up to 58°C. The thin films of the fluorine-doped VO<sub><sub>2</sub></sub>(M) showed pronounced thermochromic property and therefore is suitable for smart window applications.
