“…Cubic yttria-stabilized ZrO 2 (8 mol% yttria-stabilized zirconia (8YSZ)) transparent ceramics have a high refractive index (n) of ~2.2 [6,7], which is higher than those of most optical glasses and most oxide crystals. Based on these advantages, 8YSZ transparent ceramics are expected to serve as the multifunctional material [8][9][10][11], in particular, as optical lenses [12], windows [2], and biomedical prostheses [5,13].…”

Fine grained 8 mol% yttria-stabilized zirconia (8YSZ) transparent ceramics with high optical and mechanical properties were fabricated by air pre-sintering and hot isostatic pressing (HIP) using commercial 8YSZ powders as the raw material. The pre-sintered ceramics with fine grains and appropriate relative density play a key role to achieve high transparency and suppressed grain size after HIP post-treatment at relatively low temperatures. With the increase of HIP temperature from 1350 to 1550 °C, the in-line transmittance of 8YSZ ceramics at 600 nm increases from 56.9% to 71.5% (2.5 mm in thickness), and the average grain size increases from 2.4 to 16.3 µm. The corresponding bending strength of 8YSZ transparent ceramics decreases from 328±20 to 289±19 MPa, the hardness (H) decreases from 12.9±0.1 to 12.5±0.2 GPa, and the fracture toughness (KIC) decreases from 1.30±0.02 to 1.26±0.03 MPa·m1/2. Systematical investigations were carried out to study the combination of high optical transparency and excellent mechanical properties in 8YSZ ceramics.

“…For decades, PET scanners employed BGO as the scintillator detector component, but the relatively low light yield (9000 photons per MeV) and decay time (300 ns) limited further improvements to this imaging technique. 163 This prompted the development of Lu 2 SiO 5 :Ce 3+ (LSO), which has a much higher light yield (26 000 photons per MeV) and faster decay time (40 ns) than BGO. Similar crystals such as Gd 2 SiO 5 :Ce 3+ (GSO) were also developed, but GSO has a signicantly lower light yield (7600 photons per MeV) with a comparable decay time (60 ns).…”

“…Since color is an important feature in the fields of electronics, decoration, and jewelry, in addition to mechanical properties, the study of color in ZrO 2 materials is also of importance and interest 18,19 . In recent years, the application of colored 3YSZ ceramics has expanded into a smart terminal, dental restoration, colored decoration, and other potential fields, which is attributed to the brilliant luster, excellent mechanical properties, and favorable biocompatibility of the materials 20–22 . Nowadays, in addition to white ceramics, ceramics with other colors such as black, red, blue, etc.…”

To broaden the applications of yttria‐stabilized zirconia (YSZ) in mobile phone back panels and high‐end decorative materials, the 3 mol% YSZ (3YSZ) ceramics doped with erbium oxide (Er2O3) as colorant were successfully sintered at 1250 and 1350°C in air. The influences of Er2O3‐doping concentration and sintering temperature on the phase, microstructure, color, and mechanical properties of the pink Er2O3‐3YSZ ceramics were investigated. As the Er2O3 concentration increased, the redness value a* gradually increased, while the yellowness value b* and the lightness value L* gradually decreased. The highest value a* and b* of Er2O3‐3YSZ ceramics reached absolute values of 15.2 and 4.5, respectively. The effect of Er2O3 concentration is also depicted in detail, which also affects the mechanical properties including hardness and fracture toughness of the ceramics. The maximum hardness and fracture toughness of Er2O3‐3YSZ ceramics reached 13.9 ± 0.3 GPa and 6.21 ± 0.20 MPa·m1/2, respectively. The hardness of the ceramics exceeds 12.5 GPa, which is the required market index for further practical application. This work provides a method for preparing 3YSZ ceramics with excellent mechanical properties and bright pink color, which has the potential to be used in the fields of advanced and superior electronics in particular.
