Investigation of structural and optical properties of CaTiO3 powders doped with Mg2+ and Eu3+ ions
(Elsevier B.V., 2015-10-25)
In this work, CaTiO3 powders doped with Mg2+ ions and CaTiO3 powders co-doped with Mg2+ and Eu3+ ions were prepared by the polymeric precursor method (PPM). These powders were characterized by different characterization ...
Disruption of the chemical environment and electronic structure in p-type Cu 2O films by alkaline doping
(Journal of Physical Chemistry C Volume 116, Issue 25, 28 June 2012, Pages 13524-13535, 2012-06)
In this work we present an experimental and theoretical study of Cu 2O films doped with alkaline ions (Li +, Na +, K +, and Cs +) prepared by Cu anodization. By X-ray photoelectron spectroscopy we determined dopant ...
Effect of Mn-site doping on the magnetotransport properties of the colossal magnetoresistance compound La2/3Ca1/3Mn1-xAxO3 (A=Co, Cr; x≤0.1)
(American Physical Society, 2000-09)
In this paper we show the effect of Mn site substitution (≤10%) by Co and Cr on the magnetotransport properties of ceramic samples of La2/3Ca1/3MnO3. Resistivity, magnetization, and magnetoresistance were systematically ...
K- and Cu-doped CaTiO3-based nanostructured hollow spheres as alternative catalysts to produce fatty acid ethyl esters as potential biodiesel
(2020-09-05)
New functional polycation oxide-type catalysts were synthesized by the ultrasonic spray-pyrolysis method. The catalytic activity in the production of fatty acid ethyl esters (FAEE's) using soybean oil was studied. Catalysts ...
Synthesis and Study of Fe-Doped Bi2S3 Semimagnetic Nanocrystals Embedded in a Glass Matrix
(Mdpi Ag, 2017)
Iron-doped bismuth sulphide (Bi2-xFexS3) nanocrystals have been successfully synthesized in a glass matrix using the fusion method. Transmission electron microscopy images and energy dispersive spectroscopy data clearly ...
Synthesis route for cesium and thiocyanate doped halide perovskite thin films for a new generation of solar cells
(Universidad de La Sabana, 2022-07-09)
A novel, efficient, low-cost, and long-term lifetime photovoltaic technology is essential for accelerating the energy transition to renewable energy sources. Perovskite thin films stand out as promising photovoltaic ...
La3+ doping of the Sr2CoWO6 double perovskite: A structural and magnetic study
(Academic Press Inc Elsevier Science, 2008-11)
La-doped Sr2CoWO6 double perovskites have been prepared in air in polycrystalline form by solid-state reaction. These materials have been studied by X-ray powder diffraction (XRPD), neutron powder diffraction (NPD) and ...
