gained a constantly growing interest in this field, due to their ability to tune the material properties according to the oxidation state. Among them, vanadium pentoxide (V 2 O 5 ) exhibits both anodic and cathodic coloration, and thus the reversible lithium ion insertion/ extraction processes lead to not only reversible changes in optical parameters but also multicolor changes for esthetics in the voltage range of AE1 V. [1][2][3] Also, it was suggested that a structure with well-aligned atomic planes along z-direction is very favorable for intercalation of hosts for Li ions, such as in rechargeable batteries and electrochromic devices. [2,4,5] In addition, such a wellaligned structure would also enhance the Liþ diffusion through the solvent.An efficient way to enhance the intercalation process of Li atoms in batteries or electrochromic devices is the fabrication of nanostructured layers with well-aligned atomic planes along z-axis. Different methods were proposed to obtain nanostructured V 2 O 5 , such as electrospinning of V 2 O 5 nanofibers, electrostatic spray deposition, deposition of V 2 O 5 nanowires from chemical vapor transport, dip coating, and spray pyrolysis technique. [6][7][8] Regarding spray pyrolysis technique, this has been proved to be

“…[ 36 ] The lower frequency vibration at 998 cm −1 is due to the VO stretching vibration mode of thin films. [ 37 ] On further increase in annealing temperature to 350 and 450 °C, the peak at 267 cm −1 was shifted to 262 cm −1 , which is related to the VO bending vibration of V 2 O 5 . This inference is consistent with the XRD result.…”

“…Etemadi et al [10] synthesized films by the sol-gel method and reported an enhancement in the electrochromic behavior of the tetragonal β-V 2 O 5 by Co-doping. Darrodi et al [11] prepared V 2 O 5 films from spray pyrolysis and showed that the increase in the nozzle to substrate distance induced formation of the tetragonal β-V 2 O 5 phase. The metastable β-V 2 O 5 phase can be prepared using physical techniques, especially sputtering; however, it is formed by post-annealing at high temperatures [12,13].…”

Herein, V2O5 thin films were deposited through O2-reactive radio frequency (RF) magnetron sputtering using a metallic vanadium arget without external heating on a glass substrate. The influence of the RF power and O2 content on phase formation was investigated, and the percentage of the phase volume was related to the electrical and optical properties of the films. These films were composed of a mixture of α and β phases of V2O5, and the coexistence of monoclinic (βм) and tetragonal (βт) symmetries of the β-phase structure was observed. The phase of the film deposited at 100 W RF power with 10% O2 was βт. Increasing the RF power to 150 W led to the development of the βм phase in the film. At 200 W, the obtained film was a mixture of βм- and α-V2O5 phases, and the film produced with an O2 content of more than 10% was a mixture of three phases: βт-, βм-, and α-V2O5. Further increase in the O2 content decreased the βм-phase volume but increased the βт-phase volume. The electrical resistivity and optical properties depended on the phase volume. Furthermore, the relationship between the phase volume and film properties is presented.
