Nontemplate Synthesis of CH3NH3PbBr3 Perovskite Nanoparticles
(American Chemical Society, 2014-01)
To date, there is no example in the literature of free, nanometer-sized, organolead halide CH3NH3PbBr3 perovskites. We report here the preparation of 6 nm-sized nanoparticles of this type by a simple and fast method based ...
Selectivity in UV photocatalytic CO2 conversion over bare and silver-decorated niobium-tantalum perovskites
(Elsevier Science, 2021-02-01)
The hydrothermal synthesis of the perovskites NaNbO3, NaTaO3 and the intermediate composition NaNb0.5Ta0.5O3, as CO2 conversion photocatalysts is reported. Among them, the niobate shows the most promising performance under ...
Electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6
(IOP Publishing, 2014-04)
In this work, we present a detailed study of the structural and the electronic structure of the double perovskite Ba2Er(Nb,Sb)O 6. All calculations were performed with the Full-Potential Linear Augmented Plane Wave method ...
Spin reorientation, magnetization reversal, and negative thermal expansion observed in RFe0.5Cr0.5O3 perovskites (R = Lu,Yb,Tm)
(American Physical Society, 2016-10)
Three members of the perovskite family RFe0.5Cr0.5O3 (R = Lu,Yb, and Tm) have been synthesized and characterized. A systematic study of the crystal and magnetic structures was performed by neutron powder diffraction combined ...
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 ...
Giant and Tunable Optical Nonlinearity in Single-Crystalline 2D Perovskites due to Excitonic and Plasma Effects
(Wiley VCH Verlag, 2019-07)
Materials with large optical nonlinearity, especially in the visible spectral region, are in great demand for applications in all-optical information processing and quantum optics. 2D hybrid Ruddlesden−Popper-type halide ...
Ferrimagnetic order in the insulating Sr3Fe2ReO9 double perovskite

NOx trapping and soot combustion on BaCoO3-y perovskite: LRS and FTIR characterization
(Elsevier Science, 2005-04)
The BaCoO3-y perovskite-type mixed oxide is studied for both trapping of NOx and combustion of diesel soot. The starting material consists of a stoichiometric mixture of Ba and Co nitrates. Different crystalline phases are ...
Study of double perovskite La2B(II)MnO6 (B: Ni, Co, Cu) as electrode materials for energy storage
(Springer, 2020-03)
In this paper, the study of the potential capacity of energy storage in supercapacitors containing oxide La2B(II)MnO6 (with B = Cu, Co, Ni) as the electrode material is presented. The mixed oxides are prepared by route of ...
Effects of aging on the electrical resistivity of La1-xBxCoO3 perovskites (B = Sr, Ca, Ba; 0.20 ≤ x ≤ 0.30)
(Elsevier Science Sa, 2000-04)
A study of the reliability of the title compounds as a basis for magnetoresistive sensors is presented. For this purpose we have carried out long-term systematic studies of the evolution of the resistive and magnetic ...
