High-entropy rare-earth (RE) zirconates with pyrochlore structure were successfully fabricated by pressureless and spark plasma sintering. RE2Zr2O7 compound nominal composition (La0.2Y0.2Gd0.2Nd0.2Sm0.2)Zr2O7 was prepared simple glycine nitrate procedure (GNP). GNP process yielded powders low crystallinity after subsequent calcination, well crystalline ceramics formed. During calcination defective fluorite (F-RE2Zr2O7) crystal (Py-RE2Zr2O7) structures coexist. Formation of pure occurs...
In this manuscript, down-conversion nanopowders of SrGd2O4 doped with different concentrations either Dy3+ or Sm3+ ions were examined in detail. All samples prepared via glycine-assisted combustion method, primarily burned at 500?C for 1.5 h and additionally calcined 1000?C 2 h, ambient room temperature. The XRD analysis showed that all crystallize as single phase the orthorhombic lattice SrGd2O4. TEM determined high degree crystallinity grain size approximately 200 nm 150 For both SAED...
