Oxidative coupling of methane over Y2O3 and Sr–Y2O3 nanorods
Reaction Kinetics, Mechanisms and Catalysis, 2021Y2O3 nanorods were prepared via a hydrothermal method. A series of Sr-modified Y2O3 nanorods (Sr–Y2O3–NR) with a Sr/Y molar ratio of 0.02–0.06 were synthesized by an impregnation method, and studied with respect to their performance in the oxidative coupling of methane (OCM).

Synthesis and characterization of rod-like Y2O3 and Y2O3:Eu3+
Journal of Materials Science, 2003Y2O3 rods 100 to 200 nm in diameter and 10 to 20 μm in length are accessible via polyol-mediated synthesis of a precursor material with similar shape. By heating of Y(CH3COO)3 · xH2O and a defined amount of water at 190°C in diethylene glycol, the rod-like precursor material is formed. Infrared spectroscopy (IR), differential thermal analysis (DTA) and

High-pressure induced phase transitions of Y2O3 and Y2O3:Eu3+
Applied Physics Letters, 2009We investigated high-pressure induced phase transitions in Y2O3 and Eu-doped Y2O3 (Y2O:Eu3+) using angular dispersive synchrotron x-ray diffraction, Raman spectroscopy, and photoluminescence (PL). With increasing pressure, we observed a series of phase transformations in Y2O3:Eu3+, which followed a structure sequence of cubic→monoclinic→hexagonal ...

Abstract The Y2O3: Tm/Yb, Y2O3: Tm/Yb@Y2O3: Yb and Y2O3: Tm/Yb@Y2O3: Yb@Y2O3: Er/Yb thin films are successfully prepared via spin-coating method. The surface grain size of the thin films is changed by multiple calcinations. The up-conversion luminescence emission of the thin films under 980 nm excitation is improved through two methods, including the
