• Study on structural and optical properties of thermally evaporated MoO$_3$ thin films

Molybdenum trioxide (MoO$_3$) thin films are grown on ITO-coated glass substrates by thermal deposition technique under the presence of oxygen partial pressure (PO$_2$) about 2 ${\times}$ 10$^{–3}$ mbar at various substrate temperatures to enhance electrochromic efficiency. Even at room temperature, the experimental films were crystalline, and crystallinity increased as the substrate temperature ($T_s$) was raised to 150°C. It is noted that the uniform spherical structure was transformed to a needle-like structure at $T_s$ = 150°C. The transmittance of the films improved with substrate temperature, and corresponding bandgap values were measured. The films grown at $T_s$ = 150°C reported the highest colouration efficiency.
