A smart meta-superconductor Bi(Pb)SrCaCuO (B(P)SCCO) may increase the critical transition temperature (TC) of B(P)SCCO by electroluminescence (EL) energy injection inhomogeneous phases. However, amplitude ?TC (?TC=TC?TC,pure) TC is relatively small. In this study, a with different matrix sizes was designed. Three kinds raw materials particle were used, and series Y2O3:Sm3+, Y2O3, Y2O3:Eu3+, Y2O...

Rare-earth phosphors are commonly used in display panels, security printing, and fluorescent lamps, and have potential applications in lasers and bioimaging. In the present study, Eu3+- and Dy3+-codoped uniform-shaped Y2O3 submicron particles were prepared using the urea homogeneous precipitation method. The structure and morphology of the resulting particles were characterized by X-ray diffrac...

Bismuth and zinc co-doped Y2O3 samples are synthesized by sol-gel method using ammonium hydroxide as a precipitating agent. Structural analysis is done by XRD, SEMEDAX and the optical properties are analysed by FTIR, UV-Vis absorption studies and photoluminescence (PL) studies. UV-Vis absorption studies show absorption only around 340 nm whereas PL shows peaks around 401 nm, 680 nm and 1020 nm ...

Solid Li-ion electrolytes used in all-solid-state lithium-ion batteries (LIBs) are being considered to replace conventional liquid electrolytes that have leakage, flammability, and poor chemical stability issues, which represents one major challenge and opportunity for next-generation high-energy-density batteries. However, the low mobility of lithium ions in solid electrolytes limits their pra...

Yttria-stabilized zirconia YSZ is modeled using a cluster expansion statistical thermodynamics method built upon a density-functional theory database. The reliability of cluster expansions in predicting atomic ordering is explored by comparing with the extensive experimental database. The cluster expansion of YSZ is utilized in lattice Monte Carlo simulations to compute the ordering of dopant a...

The work is devoted to the study of optical and thermophysical properties promising materials for nuclear power a new generation - inert matrices dispersed fuel based on ZrO2 – CeO2 (ZCO) doped with Y2O3. Interest in this class due great prospects field replacing traditional type uranium-free fuel, which technological solution using plutonium as fissile element, placed matrix oxide or nitride c...

Y2O3/Y2O2S:Eu3+ nanocomposites were successfully prepared by reducing Y2O3:Eu3+ nanocrystals. The obtained Y2O3/Y2O2S:Eu3+ nanocomposites not only can emit enhanced red luminescence excited at 338 nm, but also can be used to improve the efficiency of the dye sensitized solar cells, resulting an efficiency of 8.38%, which is a noticeable enhancement of 12% compared to the cell without Y2O3/Y2O2S...

Solid solutions of CeO2 with Yb2O3, Y2O3, Sm2O3, Gd2O3, La2O3, Nb2O5, Ta2O5, and Pr6O11 were prepared by sol-gel methods. All of the samples exhibited a single, cubic phase in x-ray diffraction and the lattice parameters were consistent with formation of the solid solutions. Surprisingly, all of the mixed oxides exhibited a much lower catalytic activity for n-butane oxidation than that of pure ...

We report the epitaxial growth and superconducting properties of Y2O3-added YBa2Cu3Ox (YBCO) films grown on SrTiO3-buffered MgO substrates by pulsed-laser deposition using surface-modified YBCO targets. Areas of Y2O3 sectors on the YBCO target were increased to 5.44% and 9.22% of the total YBCO pellet in order to find a correlation between the Y2O3 content, morphology, and the pinning propertie...
