Abstract

This study investigates the effects of neutron irradiation on nanocrystalline anatase (TiO₂) using electron paramagnetic resonance (EPR) spectroscopy. Neutron irradiation doses of 1.6 × 10¹⁵, 8 × 10¹⁵, 4 × 10¹⁶, and 2 × 10¹⁷ n/cm² were applied to TiO₂ samples, and changes in the EPR spectra were analyzed to explore the transmutation of titanium (Ti) atoms into vanadium (V). The results reveal that the irradiation induces the conversion of ⁵⁰Ti to ⁵¹V via neutron capture, accompanied by the formation of oxygen and titanium vacancies. The intensity of the EPR signal decreases with increasing neutron dose, indicating that the formation of ⁵¹V isotopes and other irradiation-induced effects influence the material's paramagnetic behavior. The study provides insights into the transmutation process and highlights the potential of neutron irradiation for modifying the properties of TiO₂, with implications for photocatalytic applications and radiation-resistant materials.
