The use of electronic devices that incorporate multilayer ceramic capacitors (MLCCs) is on the rise, requiring materials with good electrical properties and a narrow band gap. This study synthesized yttrium-substituted barium titanate (Ba 1−x Y x TiO 3 , BYT) using a sol−gel process at 950 °C with varying concentrations of yttrium (0 ≤ x ≤ 0.3). X-ray diffraction analysis showed that the tetragonal phase became less pronounced as the yttrium content increased. The samples had varying grain sizes and porosity, with the BY30%T sample having the narrowest band gap at 2.21 eV. The BYT ceramic with 30% yttrium had a thermal conductivity of up to 7 W/m K and an electrical conductivity down to 0.002 (Ω cm) −1 at 180 °C. The current−voltage characteristics of the BYT MLCC were also studied, showing potential use in next-generation high-capacity MLCCs. This work presents BYT as a promising material for these types of capacitors.

“…Recently, borate glasses have a great attention due to their desirable features including facile and low-cost preparation, greatly tunable properties, controllable composition, low melting-point, excellent glass formation, and transparency. The unique and outstanding properties of borate glasses endow them beneficial importance in many applications such as radiation shielding [1], energy storage [2], optoelectronic device [3], and light emitting diode [4]. The benefits of incorporation of lithium oxide are reduction of the melting point and enhancement of ionic conduction.…”

Improvement of optical and electrical properties of borate glasses is a great demand for upgrading optoelectronic devices. Additionally, the transformation of borate glasses to nanostructured glass-ceramics endows them with outstanding beneficial properties to widen their application range. Herein, novel borate glass compositions are synthesized by the facile melt quenching method. The influences of V2O5-incorporation and nanocrystallization on the structural, optical, and electrical properties of the investigated cerium borate glasses are studied. The heat-treatment process promotes the precipitation of CeO2 and VCeO4 nanocrystals in the glass network. Linear and high dependence of the band gap of the as-prepared glasses on the V2O5 concentration is observed. A narrow band gap (about 1.6), which lies in the range of ideal bandgaps for two-junction photovoltaic cell applications, is achieved. Strong absorption in the visible and/or UV regions is attained for the studied samples, which is beneficial to shield laser emissions (up to 794 nm) and/or protect against the hazard of UV radiation. High DC conductivity (about 3 × 10-6 S/m) is approved for the glass sample containing V2O5 content of 10 mol%. The investigated glasses and nanostructured glass-ceramics are recommended as promising candidates for UV-protection sunglasses, laser safety, visible light irradiation photocatalyst, and next-generation semiconductors.
