Effect of Eu/Sr Ratios on Ferroelectric and Fluorescent Properties of Eu-Substituted Strontium Bismuth Tantalate Films

Autor: Yusuke Ohtani, Koji Aizawa

Publikováno v: Japanese Journal of Applied Physics. 47:7549-7552

The ferroelectric and fluorescent properties of Eu-substituted strontium bismuth tantalate (Eu-SBT) films grown on Pt/Ti/SiO2/Si substrates by spin coating were investigated. The polycrystalline Eu-SBT films with Aurivillius phases were grown at Eu/S

Ferroelectric and Luminescent Properties of Electroluminescence Devices Using Ferroelectric Polymer-Phosphor Composite Films

Autor: Koji Aizawa, Yusuke Ohtani

Publikováno v: Key Engineering Materials. 388:137-140

We fabricated and characterized electroluminescence (EL) devices using ferroelectric polyvinylidene fluoride/trifluoroethylene (PVDF/TrFE) copolymer composites mixed with Mn- and Cu-activated ZnS phosphor particles. Spin-coated polymer composite film

Ferroelectric and Luminescent Properties of Eu-Doped SrBi2Ta2O9Films

Autor: Koji Aizawa, Yusuke Ohtani

Publikováno v: Japanese Journal of Applied Physics. 46:6944-6947

Sr-deficient and Bi-excess strontium bismuth tantalate (SBT) films doped with Eu atoms with concentrations from 1.25 to 5 mol % (SBT:Eu) were grown on Pt/Ti/SiO2/Si substrates by spin coating. The crystallinity of the SBT:Eu films was characterized b

Autor: Naoyoshi Kubota, Yusuke Ohtani, Yuichi Furuyama, Shimpei Hamamoto, Akira Taniike, Akira Kitamura

Publikováno v: Radiation Physics and Chemistry. 69:171-178

MeV proton beams have been successfully applied as ionizing radiation to induce graft polymerization of acrylonitrile to prepare amidoxime-type adsorbents on polyethylene film substrates. Dependence of degree of grafting (DG) on the pre-irradiation p
