Nanostructured crystals of partially yttria-stabilized and Nd3+ doped zirconia: Structure and luminescent properties

In-situ synthesis of Sc2W3O12/YSZ ceramic composites with controllable thermal expansion

“…The composites just have tetragonal ZrO 2 and orthorhombic Sc 2 W 3 O 12 's characteristic peaks and no other crystalline phase is detected, indicating complete formation of Sc 2 W 3 O 12 / YSZ composites. The mechanism is that Y 3 þ stabilizer can replace the Zr 4 þ in ZrO 2 and form substitutional solid solution which can hinder the tetragonal-to-monoclinic transformation, thereby reducing the phase transition temperature [22]. Thus, the using Y 3 þ stabilizer can obtain the metastable tetragonal-ZrO 2 ceramic composites at room temperature.…”

Phase composition and spectral-luminescent properties of yttrium partially stabilized zirconia crystals doped with Nd2O3 and CeO2

“…In [19][20][21], it was shown that the existence of two tetragonal phases with differing tetragonality (с/a) in YSZ crystals can be revealed using X-ray diffraction. Figure 2 presents the diffraction patterns in the region of (006) and (600) reflections of СuK α -radiation…”

“…It was also found that Nd 3+ ions in YSZ crystals 0.8Nd 2 O 3 -2.0YSZ sit in the transformable t phase. The YSZ sample ZrO 2 -2.8 mol % Y 2 O 3 -0.22 mol % Nd 2 O 3 is characterized by the presence of Nd 3+ centers in both (transformable and nontransformable) phases, which may be caused by the synthesis conditions or other specific features of YSZ crystals of this composition [21].…”

“…In [21], we studied the structure, phase composition, and spectral-luminescent properties of YSZ crystals doped with Nd 3+ ions. The results of X-ray diffraction studies reported in the present work testify that the YSZ crystals containing 2.…”
