the 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 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...
