Phase stability and properties of Bi6Te2O13+delta (delta=0 or 2)
(Elsevier B.V., 2021-03-15)
The crystalline Bi6Te2O15 and Bi6Te2O13 phases with orthorhombic and cubic symmetries, respectively, were synthesized by solid-state reaction synthesis. A study of the thermal stability of both phases was carried out, being ...
Síntese e caracterização óptica de vidros da família TeO2 -B2O3 -(Bi2O3 ou WO3)
(Universidade Estadual Paulista (Unesp), 2018-08-30)
Vidros a base de óxidos de metais pesados (TeO2, WO3, Bi2O3) apresentam alto índice de refração, altos valores de não-linearidade óptica e alta constante dielétrica. Essas propriedades físicas possibilitam diversas aplicações, ...
Crystal structure and second harmonic generation in Bi2TeO5: An X-N study from synchrotron and neutron diffraction data
(Academic Press Inc Elsevier Science, 2019-08)
Bi2TeO5 has been obtained in polycrystalline form via solid state reaction and structurally characterized from both synchrotron and neutron powder diffraction data, enabling the precise determination of the atomic positions. ...
Estudo do efeito de CdO e Bi2O3 no processo de nucleação e crescimento de cristais em matrizes vítreas [TeO2WO3] (CdO;Bi2O3)
(Universidade Estadual Paulista (Unesp), 2012-06-18)
Apresentamos os resultados de estudos de cristalização de possíveis crescimentos de cristais semicondutores de óxido de telúrio (CdTe) e óxido de bismuto (Bi2O3) no sistema de vidro 20WO3-80TeO2 (TW). Estes trabalho ...
2D Nanosheet Paint from Solvent-Exfoliated Bi2Te3 Ink
(American Chemical Society, 2017-09-09)
Embedding 2D layered materials into polymers and other materials as composites has resulted in the development of ultrasensitive pressure sensors, tunable conductive stretchable polymers, and thermoelectric coatings. As a ...
Photovoltaic Effect In Bi2teo5 Photorefractive Crystal
(AMER INST PHYSICSMELVILLE, 2015)
Infrared-to-visible upconversion emission in Er3+ doped TeO2-WO3-Bi2O3 glasses with silver nanoparticles
(AMER INST PHYSICSMELVILLE, 2013-08-02)
The influence of silver nanoparticles (NPs) on the frequency upconversion luminescence in Er3+ doped TeO2-WO3-Bi2O3 glasses is reported. The effect of the NPs on the Er3+ luminescence was controlled by appropriate ...
Fabrication of Yb3+/Er3+ codoped Bi2O3-WO3-TeO2 pedestal type waveguide for optical amplifiers
(Elsevier B.V., 2014-12-01)
We report, for the first time to our knowledge, experimental results on pedestal waveguides produced with Yb3+/Er3+ codoped Bi2O3-WO3-TeO2 thin films deposited by RF Sputtering for photonic applications. Thin films were ...
