(A) DSC curve of the hydrothermal sample treated at 280 °C for 72 h (HTh1) with W-doped at 0.0 at%. (B) DSC curves for the undoped samples synthesized by the (HTh1 + Annealing) (annealing at 500 °C for 1 h in furnace) method and the (HTh2 + Annealing) (hydrothermal treated at 160 °C for 72 h) process respectively. (C) XRD patterns of the undoped samples synthesized by the designated two fabrication processes. The red column belongs to standard pattern in JCPDS card No. 65–2358 for VO2(M). (D) SEM images of the undoped samples synthesized by the designated two fabrication processes.
