Abstract

This work investigates the structural stability and atomic dynamics of high-purity Y₂O₃ nanoparticles under neutron irradiation. Experimental studies were carried out using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Raman spectroscopy. For the high symmetry cubic phase (space group Ia−3), the lattice parameters and interatomic distances were determined. It was found that upon neutron irradiation with varying intensities (4.0×10¹²–10¹⁵ n/cm²), the main symmetry of the crystalline structure is preserved and no new phases are formed. Raman spectra analysis revealed no significant changes in the frequencies of the main vibrational modes observed at 1081 and 1531 cm⁻¹. However, at high irradiation doses, an increase in the background level was detected, which is attributed to partial amorphization of the structure. The obtained results indicate the high radiation resistance of Y₂O₃ nanoparticles, making them promising materials for applications in optoelectronics and nuclear technologies.
