Structural, Morphological and Dielectric Studies of Sol Gel Derived Gd Doped SrTiO3-δ

Sol–gel derived PZT films doped with vanadium pentoxide

The present research investigated the sol–gel preparation, dielectric and ferroelectric properties of PZT films doped with 5 mol% vanadium oxide. Stable PZTV sols can be readily formed, and homogeneous, micrometer thick and pinhole-free PZTV films were obtained by using spin coating followed with rapid annealing. The X-ray diffraction patterns revealed that no parasitic or secondary phases were...

The Structural, Morphological, Optical and Photoluminescence Studies of Mn2+ Doped CdS/Zn3(PO4)2 Nanocomposites

The present study used a hydrothermal technique to synthesize undoped and Mn 2+ doped CdS/Zn 3 (PO 4 ) 2 semiconducting nanocomposite materials. Powder X-ray diffraction, scanning electron microscopy, UV-Vis diffuse reflectance spectrometer, Fourier transform- Infrared Spectroscopy-FT-IR, and photoluminescence techniques were employed to study structural, optical, and luminescence propertie...

Methane Combustion and CO Oxidation on Ag-Doped LaMn0.8Cu0.2O3±δ Mixed Oxides Prepared by Pechini and Sol–Gel Methods

Optical Studies on Sol-Gel Derived Lead Chloride Crystals

Optical characterization of lead chloride crystals prepared by sol-gel method is reported. The relevant sol-gel technique is used for the preparation of PbCl2 samples with five different types. In this paper, we report the absorption and fluorescence behaviour of pure, UV& IR irradiated and electric & magnetic field applied lead chloride crystal samples in solution phase at two different concen...

Observation of the quantum Hall effect in δ-doped SrTiO3

The quantum Hall effect is a macroscopic quantum phenomenon in a two-dimensional electron system. The two-dimensional electron system in SrTiO3 has sparked a great deal of interest, mainly because of the strong electron correlation effects expected from the 3d orbitals. Here we report the observation of the quantum Hall effect in a dilute La-doped SrTiO3-two-dimensional electron system, fabrica...
