Preparation of gas-tight strontium-doped lanthanum cobaltate by an aqueous sol-gel process
Gas-tight dense membranes of highly Sr-doped LaCoO, (such as the composition La,,, Sr 0,7 COO, chosen in this study) are difficult to prepare using usual synthesis processes. This report presents an aqueous sol-gel route using metal acetates as precursors to achieve this goal. Hydrogen peroxide and ammonia are added to the acetates precursor solution to obtain stable sol and xerogel, as well as...
متن کاملEffect of Grinding Time on Structural and Thermal Properties of Strontium-Doped Nanostructural Lanthanum
In this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. An impression of grinding time on the structural and thermal properties of Sr-doped LaMnO3 system with La1-xSrxMnO3 (x=0.2) stoichiometric ratio was investigated. The nano crystallite LSM powder with cubic structure was prepared by varying the milling time of planetary monomill ...
متن کاملLaser action in Nd(3+)-doped lanthanum oxysulfide powders.
We have investigated the stimulated emission properties of Nd(3+) doped La(2)O(2)S powders at room temperature as a function of pumping energy density, excitation wavelength, and Nd(3+) ion concentration. The absolute stimulated emission energy has been measured. Expressions for the slope efficiencies and lasing thresholds as a function of rare earth concentration and pumping wavelengths, which...
متن کاملIntrinsic Mobility Limiting Mechanisms in Lanthanum-Doped Strontium Titanate
The temperature dependent Hall mobility data from La-doped SrTiO3 thin films are analyzed and modeled considering various electron scattering mechanisms. We find that a ∼6 meV transverse optical phonon deformation potential scattering mechanism is necessary to explain the dependence of transport on temperature between 10–200 K. Also, we find that the low temperature electron mobility in intrins...
