Sol-gel synthesis of ordered mesoporous alumina.
Well-ordered mesoporous alumina materials with high surface area and a narrow pore size distribution were synthesized using a sol-gel based self assembly technique.
متن کاملthe sol–gel technique
The sol–gel technique is a highly flexible technique for fabrication of oxide glasses, and various researchers have previously reported fluorescence studies of Er-doped sol–gel films and monoliths. Here we report the fabrication of Er-doped strip-loaded sol–gel silicate waveguides, using a silica–titania–alumina host composition, and Er concentrations up to f1.1=10 Er rcm, for possible applicat...
متن کاملUsing Sol Gel Technique
This paper presents experimental analysis and results of GaN (being a III-V semiconductor) doped with Ferrite elements synthesized using Sol-Gel technique which are carried out at National Chemical Laboratory, Pune Maharashtra. The GaN is employed as dopant for x=1 and x=5, in the formula Ga(2x) N Fe2(49-x) O3 . A non-spinel ferrite system ( Fe2 O3) is chosen for our study. The XRD (Structural)...
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....
