Electrochromic Properties of WO3 Film by Spin-coating
Large-scale promotion of "smart windows" is to conform to the trend of sustainable development. Tungsten trioxide(WO
3
) is an important electrochromic material for producing "smart window" but the mechanism of regulating the electrochromic properties of WO
3
thin films remains to be further studied. WO
3
films were prepared by spin-coating process. The thickness of films was measured by surface profiler. The crystallinity of films was measured by X-ray diffraction(XRD) and the surface morphology was measured by atomic force microscope(AFM) and scanning electron microscope(SEM). Finally
the transmittance of the films was measured by spectrometer. The experiment results indicated that the thickness of the films increased from 9.7 nm to 33.3 nm with the solution concentration increasing(0.2 mol/L to 1.0 mol/L)
and the transmittance modulation capability of this film increased from 0% to 37.0%. The thickness of multiple spin-coated films increased linearly
and goodness of fit(
R
2
) was 0.98. After 5 times of spin-coating
the transmittance modulation capability reached 51.3%. Both changing the concentration of solution and the times of spin-coating are the effective means to regulate transmittance modulation capability and it is of great significance to accurately regulate the transmittance modulation capability of the film to design the electrochromic devices for different application scenarios.
