Electrochromic Properties of Lithium Vanadate Doped Tungsten Trioxide Film

Abstract:

Lithium vanadate doped tungsten trioxide films were coated on conducting fluorine doped tin oxide substrate by the sol-gel and dip coating methods using lithium vanadate and peroxotungstic acid sol. The concentration of lithium vanadatewas varied and the effects of lithium vanadate on morphology, microstructure and electrochromic properties of WO3 film were investigated. The synthesized tungsten trioxide with 10 wt.% lithium vanadate can be identified as amorphous structure. It observed that the crystallinity of the films are increase and more smooth when Li concentration increased and exhibits excellent properties in electrochromic performance in terms of diffusion coefficient is about as 2.6×10-9 cm2s-1 with the potential scan from -1.0 to +1.0 V as a scan rate of 100 mVs-1 in 0.5 M H2SO4 solution.
