Synthesis and characterization of nanocrystalline spinel Zinc ferrite prepared by sol-gel auto-combustion technique
Sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. In this work, nanosize (d) powders with compositions of ZnFe2O4 were synthesized by sol–gel combustion method. The puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦C for 4 h. These powders are characterized by X-ray diffraction and scanning electron microsco...
متن کاملCharacterization of Pure and Antimony Doped SnO2 Thin Films Prepared by the Sol-Gel Technique
Pure and antimony doped SnO2 thin films have been prepared by the sol-gel dip coating technique on glass substrate using starting material SnCl2.2H2O as a host and SbCl3 as a dopant. Our experimental results revealed that, the quality of the coated films on the glass depends on process parameters. The effect of annealing temperature, dipping numbe...

متن کاملHybrid polysaccharide-silica nanocomposites prepared by the sol-gel technique.
New monolithic nanocomposite silica biomaterials were synthesized on the basis of various natural polysaccharides and recently introduced completely water-soluble precursor tetrakis(2-hydroxyethyl) orthosilicate. The sol-gel processes were performed in aqueous solutions without the addition of organic solvents and catalysts. The silica polymerization was promoted by the polysaccharides through ...
متن کاملZnO films prepared by modified sol-gel technique
Zinc oxide films with different thicknesses have been synthesized by modified sol-gel technique. The films are polycrystalline in nature with average grain size between 32 and 57 nm. The thicker films are less strained than the thinner ones. The optical band gap of the films is ~ 3.22 eV. PL spectra are dominated by a strong luminescence peak at ~387 nm followed by a low intensity peak ~469 nm....
