Transparent fresnoite(Ba2TiSi2O8) glass-ceramics considered as a new type of non-linear optical materials have been prepared by controlled heat treatment in the system xK2O-(33.3-x)BaO-16.7TiO2-50SiO2(0≤x≤20 mol%), and optical properties were investigated. The glassy nature was analyzed by differential thermal analyses. The transparency of glass-ceramics was variable and controllable by the processing parameters like time and temperature. The transparent glass-ceramics showed second harmonic generation (SHG) when irradiated by a 1064nm laser beam (Nd:YAG). The SHG intensity was compared with a

In this study, the parent glass with 20Na2O- 80GeO2- 0.1 MnO2, in mol% composition is prepared via conventional melt-quenching, and the devitrification of the glass is induced by thermal treatment.

A new, transparent antimony-tellurite glass and glass-ceramic systems doped with Nb2O5 have been prepared by using the conventional melt quenching method and heat treatment process, respectively. Various physical, optical and structural studies were reported through XRD, TEM, SEM, ultraviolet-visible, Raman, infrared and ESR investigations. XRD analysis of glass and glass-ceramic samples revealed their amorphous and crystalline natures, respectively. The Williamson-Hall approach was used to determine the average crystallite size of synthesised glass-ceramics and the values were found to be in

We have investigated the feasibility of using rare-earth-doped glasses in “self-filtering” optical fibers used for remote Raman spectral collection. We have derived a theoretical treatment and have used the measured relevant sample and glass parameters (e.g., optical absorption of the doped glass and ratio of the intensities of inelastic scattering to elastic scattering plus reflection) to evaluate the usefulness of such fibers. With the use of these parameters, the optical absorption bands of Ho-doped glass, in particular, are found to be sufficiently intense and sharp to enable this glass to

The heat treatment of the glass at temperatures above transition is shown to facilitate the formation of plasmonic gold nanoparticles and decrease near-infrared luminescence intensity of the ions. The formation of pre-plasmonic gold nanoparticles under the low-temperature heat-treatment leads to the increase of luminescen

In this study, antimony-doped tin oxide (ATO) thin films were fabricated by the sol–gel dip coating process on glass substrates. After the deposition process, the films were treated by Argon–plasma (Ar-400 Watt). The effect of argon–plasma treatments on the electrical and optical properties of ATO thin films was then investigated as a function of the plasma treatment time. It was found that Ar–plasma treatment increased the electrical conductivity of ATO films, but it decreased the optical transmission of ATO thin films.

Low-emissivity glass has high transmission in the visible region and high reflectivity in the infrared region. Gallium and aluminum codoped zinc oxide (GAZO) processed by hydrogen (H2) plasma treatment holds promise for fabricating good low-emissivity glass. The applied processing time is one of the key factors in plasma treatment. The GAZO films were prepared by in-line sputtering at room temperature, and the effect of using different plasma processing times on the structural, electrical and optical properties of the films were surveyed.

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, such as opalescence, transparency, etc., must be combined in order to achieve excellent esthetic effects. The optical properties of ceramic materials are mainly distinguished by different hues (e.g., A, B, C, and D) combined with translucency (e.g., high translucency (HT), medium translucency (MT), low translucency (LT), and medium opacity (MO)
