摘要
The phase composition and spectral-luminescent characteristics of yttrium partially stabilized zirconia (YSZ) crystals doped with Nd2O3 and CeO2 (ZrO2-Y2O3-Nd2O3-CeO2) are studied. X-ray diffraction shows that YSZ ZrO2-2.5 mol %Y2O3-0.2 mol %CeO2-0.1 mol %Nd2O3, ZrO2-2.03 mol %Y2O3-0.435 mol %CeO2-0.334 mol %Nd2O3, and ZrO2-2.03 mol %Y2O3-0.653 mol %CeO2-0.111 mol %Nd2O2 YSZ crystals contain two different tetragonal phases (transformable t and nontransformable 't). The spectral-luminescent properties of these crystals indicate that Nd3+ ions occupy sites mainly in the transformable (t) phase.
