Sputter deposition of yttrium–oxides

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1993
The yttrium–oxide phase diagram contains only one equilibrium compound, a Y2O3 cubic structure. The process of reactive sputter deposition is used to synthesize previously unreported, yttrium-rich oxide compounds. A planar magnetron is operated in the direct–current mode using a working gas mixture of argon–20% oxygen.

Thermochromic Behavior of Yttrium-Substituted Bismuth Oxides

ACS Applied Materials & Interfaces, 2019
High-temperature thermochromic materials are poorly explored in fundamental research, let alone applied research, although these materials may be used as low-cost, intuitively usable sensing materials in an industrial environment. Yet, only few of these materials have been described systematically.

Yttrium Surface Gradient Doping for Enhancing Structure and Thermal Stability of High-Ni Layered Oxide as Cathode for Li-Ion Batteries.

ACS Applied Materials and Interfaces, 2021
The high-nickel layered oxides are potential candidate cathode materials of next-generation high energy lithium-ion batteries, in which higher nickel/lower cobalt strategy is effective for increasing specific capacity and reducing cost of cathode ...

Green synthesis, characterization of yttrium oxide, stannous oxide, yttrium doped tin oxide and tin doped yttrium oxide nanoparticles and their biological activities

Materials Today: Proceedings, 2021
Abstract Yttrium doped tin oxide and Tin doped yttrium oxide nanoparticles were prepared by using Solanum nigrum plant extract. The obtained nanoparticles were confirmed by XRD and SEM. The antimicrobial activities of green synthesized nanoparticles were studied by using Bacillus subtilis.

Carbochlorination of yttrium oxide

Thermochimica Acta, 2010
Abstract The reaction of chlorination of a mixture composed by Y 2 O 3 and sucrose carbon was studied by thermogravimetry over a temperature range of 550–950 °C. The reaction proceeds through several successive stages. The first of them is the formation of solid yttrium oxychloride (YOCl) and subsequently the YOCl is carbochlorinated to produce YCl ...

Electronic structure of yttrium oxide

Physical Review B, 1990
The electronic structure of stoichiometric Y{sub 2}O{sub 3} is studied both theoretically and experimentally. X-ray absorption, performed through total-yield measurements at the {ital K} and {ital L}{sub II} edges of yttrium atoms and the {ital K} edge of oxygen atoms, through total-yield measurements has given access to empty states of various orbital

Thin film studies of yttrium, yttrium hydrides and yttrium oxide

Journal of Physics F: Metal Physics, 1978
Electron diffraction work has been carried out on yttrium films prepared in a vacuum of 5*10-7 Torr during evaporation. The crystal structure of thin yttrium films (300 AA thick or less) is mainly face-centred-cubic with a0=5.25+or-0.05 AA which can be attributed to cubic yttrium dihydride.

Metastability of yttrium oxides

Surface and Coatings Technology, 1993
Abstract Metastable yttrium oxide films are synthesized using reactive sputter deposition. The yttrium concentration of the as-deposited film is found to vary as a function of the sputter deposition rate. In addition to the synthesis of the cubic equilibrium phase Y 2 O 3 , oxide compounds can be formed with 40–80 at. % Y.

Luminescence of yttrium oxide

Technical Physics, 2008
Pulsed cathodoluminescence of pure and neodymium-activated Y2O3 ceramic and materials used for its synthesis (commercial Y2O3 micropowder and nanopowder obtained from it by laser evaporation) is investigated in a wavelength range of 350–850 nm. In the micropowder, four series of narrow electron-vibration bands of intrinsic luminescence centers are ...
