In this paper, we report the effect of soda lime substrate deposition temperature (T s) on the crystal structure and the metal insulator transition of VO 2 thin films. Samples were deposited at substrate deposition temperature ranging from 450 to 600 0 C by pulsed-laser deposition and characterized by x-ray diffraction and UV-VIS spectrophotometer. At a substrate temperature of 550°C, the VO 2 (100) reflection dominate the spectrum showing a change in crystalline grains orientation. The highest transition temperatures of 74 o C with the lowest hysteresis width of 11 o C were obtained on the same sample grown at a substrate deposition temperature of 500 o C and also corresponding to the largest grains size of a value of 350 nm.
