From: Synthesis and thermochromic property studies on W doped VO2 films fabricated by sol-gel method
XRD patterns of VO2 films grown on sapphire substrates, (a–c) annealed at 450, 470 and 500 °C for 4 h with nominal 1 at.%W-doping; (d–f) annealed at 470 °C for 4 h with nominal 1.5 at.%, 2 at.%W-doping and undoping. The dashed lines are guide for the eyes.
