Scintillation Properties of Ga<sub>2</sub>O<sub>3</sub> Translucent Ceramics Annealed at Different Temperatures

نویسندگان

چکیده

Annealing temperature dependence on optical and scintillation properties of the β-gallium oxide (β-Ga2O3) translucent ceramic has been investigated. The Ga2O3 was prepared by spark plasma sintering annealed in air. All ceramics showed broad emissions peaking at 390—410 nm due to recombination defect-related donors acceptors. 1000—1100°C ultraviolet emission around 350 increase transmittance which caused decrease oxygen vacancies. Under α-ray excitation from 241Am, light yield 1000°C highest among all ceramics, value 2300 photons/5.5 MeV-α.

Microstructure and Dielectric Properties of LPCVD/CVI-SiBCN Ceramics Annealed at Different Temperatures

SiBCN ceramics were introduced into porous Si₃N₄ ceramics via a low-pressure chemical vapor deposition and infiltration (LPCVD/CVI) technique, and then the composite ceramics were heat-treated from 1400 °C to 1700 °C in a N₂ atmosphere. The effects of annealing temperatures on microstructure, phase evolution, dielectric properties of SiBCN ceramics were investigated. The results revealed that α...
