“…However, the brittleness of glasses remains a problem when they are mechanically thinned to ~ 200 µm 19 . Therefore, new technology, such as the tape-casting technique, must be adopted to produce ultrathin PGC, especially when it is combined with a lowtemperature co ring process 20 . The primary advantage of the tape casting process is its ability to produce large-area, thin, at PGC green sheets 21,22 .…”

Driven by the demand for super-bright LED lights for cars, buses, and trucks, highly efficient and large-area ultrathin phosphor-glass composites (PGC) with exceptional thermal dissipation capabilities were fabricated by a combined technique of tape-casting + low-temperature cofiring process. Two kinds of ultrathin (100 μm thick) PGC plates uniformly incorporated with YAG:Ce and CaAlSiN3:Eu2+ phosphor particles and with a large size of 1044×45 mm were successfully prepared. At room temperature, photoluminescence quantum yields (PLQY) of 98.6% and 80% were achieved for the former and latter kinds of PGC glasses, respectively. Moreover, color tunable emissions were yielded in the ultrathin PGC by varying the weight ratio of different phosphors. Finally, light-emitting diodes (LEDs) encapsulated with different ultrathin PGC were demonstrated to exhibit outstanding luminous performance. When exposed to blue laser irradiation, the prepared PGC glasses demonstrated a heightened resistance to laser radiation. These unparalleled ultrathin PGC glasses could offer an unprecedented solution for the commercial applications in preparation of super bright car LED lights.

“…Advances in modern automation systems require a search for new functional materials, including nonlinear dielectrics whose properties are influenced by an external electric field. Those materials have found application in dynamic RAM, tuneable microwave devices, such as tuneable oscillators, phase shifters, reactors with a large tuneable capacitance range and low dielectric loss, transducers and sensors [1][2][3], thermistors [4], and multilayer ceramic capacitors [5].…”

The materials based on barium titanate have nonlinear dependence of polarization on the intensity of the electrical field. The properties of those materials are used when different automation elements such as primary converters, phase regulators for low and high frequencies, sensors, modulators etc. are derived. Ceramics based on barium titanate (BaTiO3) alloyed with H3BO3 and Bi2O3 have been derived and researched. The influence of the temperature of sintering on the values of the dielectric permittivity on the structural properties has been determined. The influence of the quantity of the added material on the temperature dependencies and the non-linear properties of the ceramics have been analyzed. Both legation additives decrease the sintering temperature. However, the values of the dielectric permittivity decrease while the non-linear properties of the doped barium titanate (BaTiO3) improve. The coefficient of non-linearity reaches its maximum for the H3BO3 composites, synthesized at temperature of 1100 oC.
