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.

The electronic state of thin films of yttrium, yttrium hydrides and yttrium oxide [PDF]

open access: yesSolar Energy Materials and Solar Cells, 2014
Thin films of yttrium hydride have for almost 20 years been under investigation for optoelectronic and solar energy applications due to the hydrogen-induced switching in electronic state from the metallic elemental yttrium and yttrium dihydride to the transparent semiconductor material yttrium trihydride.

Distribution of REEs and yttrium among major geochemical phases of marine Fe–Mn-oxides: Comparative study between hydrogenous and hydrothermal deposits

open access: yesChemical Geology, 2012
Mineralogy and geochemistry of the ferromanganese oxides collected from two seamounts in the Andaman Sea have been investigated with special reference to the solid phase partitioning behavior of rare earth elements (REEs).

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.
