Synthesis and Characterization of Hollow Magnetic Alloy (GdNi2, Co5Gd) Nanospheres Coated with Gd2O3
A series of new transparent and magnetic barium gallogermanate glasses in the system (x) Gd2O3 – (100-x) [20BaO?15Ga2O3?65GeO2] with x = 0, 8, 14, 18, 22 25 mol% were synthesized. Their thermal, structural properties characterized. Based on differential scanning calorimetry results, one determined composition domain exhibiting highest thermal stability toward crystallization provided a detailed...
Y2O3-stabilized ZrO2 (YSZ) has been the material of choice for thermal barrier coatings (TBCs) in past decades, yet its phase decomposition limits application above 1200 °C. In this study, Gd2O3 and Yb2O3 co-doped YSZ powders were produced, which some amounts monoclinic (m) introduced into cubic (c) matrix. XRD results showed that fabricated obtained by a solid synthesis composed m c phases, ha...
There is great technological interest in elucidating the effect of particle size on the luminescence efficiency of doped rare earth oxides. This study demonstrates unambiguously that there is a size effect and that it is not dependent on the calcination temperature. The Y₂O₃:Eu and Gd₂O₃:Eu particles used in this study were synthesized using wet chemistry to produce particles ranging in size be...
