TRANSPARENT BARIUM TITANATE GLASS CERAMIC NANOCOMPOSITES FOR OPTOELECTRONIC DEVICE APPLICATIONS

The glass crystallization process was applied to create a nanocomposite material composed of crystallites within a glass-like matrix. The structural optical and dielectric properties of crystals embedded in a glassy matrix, the BaTiO3-Na2O-B2O3-SiO2 system generated by the melt quenching process, were investigated in this study. The heat treatment procedure was used to convert the prepared glass to glass-ceramic samples at temperatures ranging from 700 to 800°C. After being quenched between stainless steel plates, the X-ray diffraction results reveal the presence of crystalline phase in a glassy matrix. Scanning electron micrography and transmission electron micrography were used to investigate the crystal morphology. The glass transition and crystallization temperatures were investigated by using the differential thermal analysis. The optical transmittance spectra in the wavelength range of 300-1000 nm were then recorded using UV-Vis spectrophotometer. A precise LCZ meter was used to measure the dielectric characteristics at various frequencies. It was demonstrated that crystallites form using a specific method, resulting in anisotropic glass ceramic. The shape and crystallinity of the produced samples influence their optical and dielectric properties.
