The Effect of Nano-Particle Formation on Radiation Resistance of Phosphate Glasses Potentially Suitable for Nuclear Waste Immobilization

The effect of nano-particles on the radiation resistance of glasses potentially suitable for nuclear waste immobilization was investigated. The glasses were investigated by means of EPR, UV-visible optical spectroscopy, RBS and TEM. EPR spectra of the samples implanted with Ti + , Cr + , Mn + , Co + and Cu + to F≤10 16 cm -2 contain the lines  typical of “isolated” Ti 3+ , Cr 3+ , Mn 2+ , Co 2+ and Cu 2+ ions in oxide glasses.
