Electrochromic TiO2, ZrO2 and TiO2-ZrO2 thin films by dip-coating method
Sol-gel processing of TiO2, ZrO2 and mixed Ti/Zr oxide thin films has been studied as application of these coatings in electrochromic devices. Their structural transformations as a function of annealing temperatures were analyzed by XRD and FTIR techniques. Electrochromic behavior of the three kind materials was investigated by cyclic voltammetry and the basic electrochromic characteristics wer...
متن کاملOptical parameter determination of ZrO2 thin films prepared by sol gel dip coating
Abstract : Zirconium Oxide (ZrO2) thin films were prepared on glass substrates by sol-gel dip coating method using Zirconium Oxychloride Octahydrate, Isopropanol and Acetyl acetone as precursor, solvent and stabilizer respectively. In the present work, the optical properties of the Zirconia thin films have been studied. Samples with different number of layers were prepared by repeating the dipp...
متن کاملSrBi2Nb2O9 Thin Films Deposited by Dip Coating Using Aqueous Solution
A new approach for SrBi2Nb2O9 (SBN) thin ®lms synthesis using aqueous solution was successfully experienced. The deposition solution was prepared from Sr±Bi±Nb mixed-citrate solution, requiring no special atmosphere and using common reagents. Films were deposited by dip coating onto Pt/Ti/SiO2/ Si(100) substrates and heat treated at temperatures ranging from 300 to 700 C. The process of formati...
متن کاملPhotocatalytic oxidation of acetone vapor on TiO2/ZrO2 thin films
The photocatalytic oxidation of acetone vapor on TiO2/ZrO2 thin films is presented in this study. Acetone conversion data collected using a non-circulating tubular reactor are analyzed using a general power law model and a Langmuir–Hinshelwood– Hougen–Watson (LHHW) model; the LHHW model provides a slightly better fit than the 1/2 order power law model. The effects of reaction temperature and re...
متن کاملLow-temperature synthesis and characterization of TiO2 and TiO2-ZrO2 photocatalytically active thin films.
Transparent TiO(2) and TiO(2)-ZrO(2) (molar ratio Zr/Ti = 0.1) thin films were produced by low-temperature sol-gel processing from nanocrystalline aqueous based solutions. The structural features and compositions of the films treated at room temperature, 100 degrees C and 500 degrees C were investigated by X-ray diffraction, X-ray photoelectron spectroscopy and thermal analysis. Addition of zir...
