摘要: Abstract We report on a study of the stability and defect structure erbia-stabilized bismuth oxide (ESB) yttria-stabilized zirconia (YSZ). Samples (Bi2O3)0.8(Er2O3)0.2 were annealed at 400–600°C in air characterized using X-ray diffraction, differen tial thermal analysis, ac impedance fluorescence spectroscopy to ascertain changes properties structure. The chemical ESB as function oxygen partial pressure various environments was investigated impedance, electron microprobe analysis. also species energy level transitions YSZ optical spectroscopy.
