Electrochromic switching of WO3 nanostructures and thin films
نویسنده
چکیده
We present transmission measurements through tungsten tri-oxide nanostructures and thin films prepared by sol–gel process on micro-contact printed substrates. Identical electrochromic switching times are found for both the nanostructures and the bulk films with equal thicknesses upon intercalation of H+ ions. We attribute the large change in the transmission through nanostructures at 632 nm, which can not be solely explained by absorption, to diffraction effects. PACS 73.40.Cg; 73.40.Mr; 78.20.-e; 78.67.n

Designing and Fabrication of Electrochromic Windows Using Tungsten Oxide Films Prepared Through Sol-gel Coating on a Glass
In this study, a sol-gel peroxotungstic acid sol was employed to deposit tungsten oxide (WO3) films by the spin-coating technique. In view of smart window applications, electrochromic windows were then designed and fabricated using a thin tungsten oxide film. For this purpose, Glass/ FTO/ WO3/ electrolyte/ FTO/Glass could be of use due to its special structure that consists of an electrochromic...
متن کاملImproving Electrochromic Properties of WO3 Thin Film with Gold Nanoparticle Additive
In this research, WO3 and Au-WO3 thin films were prepared at different temperatures using the sol gel method. The effect of gold nanoparticles (GNPs) on the electrochromic properties of WO3 was also studied. 2.5 nm GNP was synthesized through sodium citrate reduction of gold chloride in an aqueous solution. These films were characterized by XRD, SEM, TEM, and spectrophotometer analyses. The fil...

This paper proposes a suitable method for increasing effective surface area of electrodeposited WO3 thin films. This is done because effective surface area improves optical and electrochromic properties in smart windows. Therefore, we investigated precursor aging atperoxytungstate precursor (0, 24, 48 and 72 h). Experiments showed by increasing aging time of the precursor solution, larger aggre...
متن کاملHydrothermally grown nanostructured WO3 films and their electrochromic characteristics
We report the synthesis of nanostructured tungsten trioxide (WO3) films and their electrochromic characteristics. Plate-like monoclinic WO3 nanostructures were grown directly on fluorine-doped tin oxide glass substrates by a simple and low-cost crystal-seed-assisted hydrothermal method. The growth mechanism of the film is investigated. HRTEM analysis reveals the single crystalline quality of th...

Tungsten trioxide (WO3) films have been coated on indium thin oxide (ITO) conductive glass substrate, using aqueous solution of peroxotungstic acid (PTA) by the sol-gel dip coating method. X-ray diffractometery (XRD) analysis confirmed monoclinic and triclinic structure for the film and powdered WO3 respectively. Fourier transforms infrared spectroscopy (FT-IR) exhibit...
