Rietveld refinement and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method Abstract: We investigated the effect of annealing time on the structure and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method […]
Rapid hydrothermal synthesis and pH-dependent photocatalysis of strontium titanate microspheres Abstract: This manuscript describes a methodology for a rapid hydrothermal conventional synthesis of SrTiO3. The time of synthesis and use of mechanical stirring are related to […]
Light emission during electric field-assisted sintering of electroceramics Abstract: Electric field-assisted sintering has been shown to occur in ion, electron conducting as well as in insulating polycrystalline ceramics. Considerable linear shrinkage with microstructure control at temperatures lower than […]
Anomalous remnant magnetization in dilute antiferromagnetic Gd1−xYxB4 Abstract: Magnetic properties of dilute single crystals of Gd1−xYxB4 (x=0, 0.2, and 0.4) were systematically studied. These antiferromagnetic Shastry-Sutherland compounds display a remnant magnetization MRwhen field cooled below the Néel temperature TN. The […]
Fabrication and structural characterization of bismuth niobate thin films grown by chemical solution deposition Abstract: Bi3NbO7 (BNO) thin films were deposited on Pt/TiO2/SiO2/Si (100) substrates at room temperature from the polymeric precursor method. X-ray powder diffraction and […]
