Plastic deformation of dense nanocrystalline yttrium oxide at elevated temperatures [PDF]
, 2012 Nanocrystalline yttrium oxide, Y2O3 with 110 nm average grain size was plastically deformed between 800 ◦C and 1100 ◦C by compression at different strain rates and by creep at different stresses. The onset temperature for plasticity was at 1000 ◦C. Yield

Optical excitation and external photoluminescence quantum efficiency of Eu3+ in GaN [PDF]
, 2014 We investigate photoluminescence of Eu-related emission in a GaN host consisting of thin layers grown by organometallic vapor-phase epitaxy. By comparing it with a reference sample of Eu-doped Y2O3, we find that the fraction of Eu3+ ions that can emit ...

Enhancing the density of silicon carbide with the addition of nitrate-based additives [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2022 Dense monolithic silicon carbide (SiC) was successfully sintered by hot pressing at 1750ºC for 1 h under an applied pressure of 20 MPa with the addition of a nitrate-based additive. With the addition of MgO-Y2O3 and Al2O3-Y2O3 in nitrate form, a relative
