Evaluation of Photocatalytic Activity of Fe Doped TiO2 Thin Film Prepared by sol-gel hot dip-coating
The application of Fe–TiO2 photocatalysis using sol–gel method by hot–dipping technique was investigated. Then, the influences of fabrication parameters, molar ratios of Fe to TiO2, the sol temperature, poly ethylene glycol (PEG) content and the number of dipping cycles on the photocatalytic activity in visible light region were mainly studied. The experimental results revealed the sample with ...
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 کاملInterferometric monitoring of dip coating.
Dip-coated films, which are widely used in the coating industry, are usually measured by capacitive methods with micrometric precision. For the first time to our knowledge, we have applied an interferometric determination of the evolution of thickness in real time to nonvolatile Newtonian mineral oils with several viscosities and distinct dip withdrawing speeds. The evolution of film thickness ...
متن کاملRoughness of 3C-SiC thin film coating computer simulation
This paper deals with efficiency of weakly ionized gas-wall interaction which leads to follows: melting surface, clustering of vapor and melted charged drops nucleation to the solid phase. It shapes roughness of the surface coating.
متن کاملSimple push coating of polymer thin-film transistors
Solution processibility is a unique advantage of organic semiconductors, permitting the low-cost production of flexible electronics under ambient conditions. However, the solution affinity to substrate surfaces remains a serious dilemma; liquid manipulation is more difficult on highly hydrophobic surfaces, but the use of such surfaces is indispensable for improving device characteristics. Here ...
