Europium-doped barium bromide iodide
Single crystals of Ba(0.96)Eu(0.04)BrI (barium europium bromide iodide) were grown by the Bridgman technique. The title compound adopts the ordered PbCl(2) structure [Braekken (1932 ▶). Z. Kristallogr.83, 222-282]. All atoms occupy the fourfold special positions (4c, site symmetry m) of the space group Pnma with a statistical distribution of Ba and Eu. They lie on the mirror planes, perpendicul...
متن کاملThermoelectric Properties of Lanthanum-Doped Europium Titanate
The thermoelectric properties of lanthanum-doped polycrystalline perovskite-type europium titanate were measured from room temperature to 900K and compared to those of MTiO3 (M 1⁄4 Ca, Sr, Ba). The differences in the titanates were calculated in terms of the differences of A-site ion and Ti–O distance that determined the covalent bonding strength. The A-site ion appeared to have little influenc...
متن کاملSynthesis and characterization of Barium Strontium Titanate (BST) micro/nanostructures prepared by improved methods
Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over the other methods. Low processing temperature is a desired point which most of...

متن کاملAn XPS Investigation of Hydrothermal and Commercial Barium Titanate Powders
Hydrothermal and commercial barium titanate powders were examined for undesirable impurity phases. Compositional differences in the powder were evaluated using x-ray diffraction ( XRD ), x-ray fluorescence ( XRF ), and x-ray photoelectron spectroscopy (XPS). A brium-rich impurity phase, virtually undetectable by XRD, was detected via XPS. Barium impurity phase peaks were detected at binding ene...
