(MDPI, 2023)
The purpose of this study is to comprehensively analyze the influence of different fluences of irradiation with Xe23+ heavy ions on alterations in the structural, optical, and strength properties of AlN ceramics and to ...
Study of β-Ga2O3 Ceramics Synthesized under Powerful Electron Beam
(MDPI, 2023)
The synthesis of β-Ga2O3 ceramic was achieved using high-energy electron beams for the first time. The irradiation of gallium oxide powder in a copper crucible using a 1.4 MeV electron beam resulted in a monolithic ceramic ...
The Effect of Fast Kr Ion Irradiation on the Optical Absorption, Luminescence, and Raman Spectra of BaFBr Crystals
(MDPI, 2023)
In this work, using photoluminescence (PL), optical absorption (OA), Raman spectroscopy (RS), and atomic force microscopy (AFM), the radiation damage of BaFBr crystals irradiated with 147 MeV 84Kr ions to fluences (1010–1014) ...
Optical Characteristics of MgAl2O4 Single Crystals Irradiated by 220 MeV Xe Ions
(MDPI, 2023)
