In Vivo Evaluation of the Effects of Sintering Temperature on the Optical Properties of Dental Glass-Ceramics

open access: yesNanomaterials, 2022
In prosthodontics, the ability of glass-ceramics to express the optical properties of natural teeth is an important goal of esthetic restorations. Dental restorations do not merely need to be similar in color to natural teeth; proper optical properties ...

Reactive sintering of highly-doped YAG/Nd3+ :YAG/YAG composite ceramics [PDF]

open access: yesProcessing and Application of Ceramics, 2017
Multilayer YAG/Nd3+:YAG/YAG composite laser ceramics were obtained by the reactive sintering in vacuum. The effect of the neodymium ion concentration (1–4 at.%) on the formation of defects and optical quality of composite ceramics was studied.

Effect of the sintering temperature on microstructure and optical properties of reactive sintered YAG:Sm3+ ceramics

open access: yesOptical Materials: X, 2022
YAG:Sm3+ (5 аt.%) optical ceramics were obtained by the solid-state reactive sintering in the 1700–1800°C temperature range. The effect of the sintering temperature on the microstructure, phase composition and optical properties of YAG:Sm3+ ceramics has ...

Mn-Co-Ni-O thin films prepared by sputtering with alloy target

open access: yesJournal of Advanced Ceramics, 2020
The thin film of heat-sensitive materials has been widely concerned with the current trend of miniaturization and integration of sensors. In this work, Mn1.56Co0.96Ni0.48O4 (MCNO) thin films were prepared on SiO2/Si substrates by sputtering with Mn–Co–Ni

Hot pressing of Ho2O3 and Dy2O3 based magneto-optical ceramics

open access: yesOptical Materials: X, 2022
The paper presents results of a research on fabrication of magneto-optical ceramics based on Ho2O3 and Dy2O3 sesquioxides. The ceramics were made by hot pressing of powders prepared by self-propagating high-temperature synthesis. The methods and modes of

Plasmon Assisted Highly Efficient Visible Light Catalytic CO2 Reduction Over the Noble Metal Decorated Sr-Incorporated g-C3N4

open access: yesNano-Micro Letters, 2021
The photocatalytic performance of g-C3N4 for CO2 conversion is still inadequate by several shortfalls including the instability, insufficient solar light absorption and rapid charge carrier’s recombination rate.

Fabrication and optical properties of Er2-xYbxZr2O7 transparent ceramics

open access: yesOptical Materials: X, 2022
In this study, Er2-xYbxZr2O7 (x = 0–2.0) transparent ceramics were successfully prepared by vacuum sintering at 1850 °C for 6 h. The phase composition, microstructure evolution and optical properties of the as-prepared ceramics were investigated.

Optical scattering in glass ceramics

open access: yesPhilosophical Magazine, 2008
The transparency of glass-ceramics with nanocrystals is generally higher than that expected from the theory of Rayleigh scattering. We attribute this ultra-transparency to the spatial correlation of the nanoparticles. The structure factor is calculated for a simple model system, the random sequential addition (RSA) of equal spheres, at different volume

Experimental and DFT Studies of Au Deposition Over WO3/g-C3N4 Z-Scheme Heterojunction

open access: yesNano-Micro Letters, 2019
A typical Z-scheme system is composed of two photocatalysts which generate two sets of charge carriers and split water into H2 and O2 at different locations. Scientists are struggling to enhance the efficiencies of these systems by maximizing their light

Improved light transmission in nanocrystalline aluminum nitride (AlN)—Enabling a lightweight, thermal shock resistant transparent ceramic

open access: yesMaterials & Design, 2022
Optically transparent ceramics were traditionally only viable using optically isotropic materials and limited birefringent materials with small Δn such as alumina (Δn≈0.008).
