Choice of Materials for Creating Micro-OptoElectromechanical Switches for Next-Generation Communication Systems DOI: 10.22184/1993-7296.FRos.2025.19.5.400.406
The paper discusses the selection of materials for micro-opto-electromechanical switches (MOEMS) used in new generation communication systems. The focus is on the optical and electrical characteristics of materials, such as dielectric permittivity, refractive index, and bandgap. A study of the effect of these parameters on the efficiency of optical systems is carried out. Machine learning methods were used to predict the properties of materials, and promising materials with high dielectric permittivity were identified. The results obtained can be useful in the development of new methods for designing optical and radio-frequency communication components.

Crystal Scintillator With a Sensitized Circuit for Converting Ionizing Radiation Into the Visible Spectral Band DOI: 10.22184/1993-7296.FRos.2025.19.5.408.418
The inorganic compounds based on crystalline solid solutions are proposed as the materials for visually observable transformation of ionizing radiation. The energy spectra of Ca1‑xLuxF2+x: Eu2+ crystals have showed that the light output is consistently increased upon an increase in the parameter Zeffect related to the advanced LuF3 content. The efficient excitation energy transfer between the impurity rare-earth ions Eu2+ and Pr3+ in the mixed crystals of Ca1‑xLuxF2+x synthesized by the horizontal directional crystallization has been studied. The results of luminescence studies during registration of the γ-, X-ray and short-wave UVC radiation confirm the process of excitation energy transfer from the Eu2+ ions to Pr3+ in Ca1‑xLuxF2+x and allow to consider the Eu2+ ions as an efficient sensitizer of Pr3+ ions. The sensitization-enhanced radiation of Pr3+ ions converts the UV radiation of Eu2+ excited by the γ-quanta into the visible spectral band.
