Optical Properties and Upconversion Luminescence of BaTiO₃ Xerogel Structures Doped with Erbium and Ytterbium [PDF]

Gels, 2022
Erbium upconversion (UC) photoluminescence (PL) from sol-gel derived barium titanate (BaTiO3:Er) xerogel structures fabricated on silicon, glass or fused silica substrates has been studied. Under continuous-wave excitation at 980 nm and nanosecond pulsed

Computational study of (111) epitaxially strained ferroelectric perovskites BaTiO(3) and PbTiO(3) [PDF]

, 2008
The phase transition behavior of PbTiO(3) and BaTiO(3) under (111) epitaxial strain is investigated using density-functional theory calculations. From tensile strains of +0.015 to compressive strains of -0.015, PbTiO3 undergoes phase transitions from C2 ...

On the Ferroelectric to Paraelectric Structural Transition of BaTiO₃ Micro-/Nanoparticles and Their Epoxy Nanocomposites

Molecules, 2020
BaTiO3 is one of the most widely used ceramic components in capacitor formulation due to its exceptional ferroelectric properties. The structural transition from the ferroelectric tetragonal to the paraelectric cubic phase has been studied in both nano ...

Evaluation of Stereolithography-Based Additive Manufacturing Technology for BaTiO₃ Ceramics at 465 nm

Applied Sciences, 2022
A piezoceramic BaTiO3 material that is difficult for 3D printing was tested with a homemade laser-based stereolithography (SLA) setup. The high light absorbance of BaTiO3 in the spectral range of 350–410 nm makes this material hardly usable with most ...

Barium Titanium Oxynitride from Ammonia-Free Nitridation of Reduced BaTiO₃

Inorganics, 2021
We investigated the nitridation of reduced BaTiO3, BaTiO2.60H0.08, corresponding to an oxyhydride with a large concentration of O defects (>10%). The material is readily nitrided under flowing N2 gas at temperatures between 400 and 450 °C to yield ...

Preparation of BaTiO 3 by homogeneous precipitation

Journal of the European Ceramic Society, 1999
Three different methods are studied for the preparation of fine-grained BaTiO3 by homogeneous precipitation: (1)Hydrolysis of barium and titanium alkoxide precursors, in which the required water is generated by an esterification reaction; (2)Precipitation of a barium¿titanium complex as a result of thermal decomposition of Ba-EDTA; (3)Precipitation of ...

Enhanced dielectric properties and energy storage of the sandwich-structured poly(vinylidene fluoride-co-hexafluoropropylene) composite films with functional BaTiO(3)@Al(2)O(3) nanofibres

IET Nanodielectrics, 2019
Polymer-based composites with ceramic fillers could combine the advantages of both, which can be potentially used in electrical and electronic technology. In this work, the barium titanate (BaTiO(3)) nanofibres and the core–shell structured BaTiO(3)@Al(2)

Interfacial coherency and ferroelectricity of BaTiO(3)/SrTiO(3) superlattice films [PDF]

, 2007
We studied the phase transitions, domain morphologies, and polarizations in BaTiO(3)/SrTiO(3) superlattices grown on SrTiO(3) substrates. Using the phase field approach, we discovered the remarkable influence of film/substrate interfacial coherency on ...
