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, 2010Abstract 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, 1990The 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, 1978Electron 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, 1993Abstract 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.

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 ...

Thermal transformation of yttrium hydroxides to yttrium oxides
Thermochimica Acta, 1988Abstract The reaction between aqueous solutions of yttrium salts (chloride and nitrate) at constant concentration and alkaline solutions (sodium and ammonium hydroxides) were investigated under different conditions. As a result, amorphous and hexagonal yttrium hydroxides, Y(OH)3, were formed and in addition monoclinic yttrium hydroxide, α-Y(OH)3, was

Transparent yttrium oxide ceramics
Materials Research Bulletin, 1967Abstract Transparent discs of yttrium oxide, one centimeter in diameter by several millimeters thick, have been produced by hot forging under vacuum at 950°C and 10,000–12,000 psi for 48 hours. Lithium fluoride, required to produce full transparency, is eliminated during the sintering process.
