Radiation-induced valence conversion and photoluminescence of copper ions in aluminoborosilicate glasses

Copper nanoparticle and point defect formation in Cu+–Na+ ion-exchanged glass using protons of 2 MeV energy

“…Similar behavior of copper ion conversion was reported by Nishi et al , 52 who studied the effect of X-rays and γ-rays on the radio-photoluminescence (RPL) of Cu-doped aluminoboro glass silicate. In their investigation, they observed a prominent RPL phenomenon that could be attributed to the conversion of Cu 2+ to Cu + ions.…”

“…Similar effects were reported for other types of doped and irradiated glasses, in which quenching of NBOHCs was reported, which might predominate especially in cases where a significant quantity of the additive ions preexist in the lower oxidation state. 16,65 Similar behavior of copper ion conversion was reported by Nishi et al, 52 who studied the effect of X-rays and γ-rays on the radio-photoluminescence (RPL) of Cu-doped aluminoboro glass silicate. In their investigation, they observed a prominent RPL phenomenon that could be attributed to the conversion of Fig.…”

“…This is principally due to the presence of Cu + ions that, unlike the Cu 2+ ions, are non-luminescent, and emit bright luminescence in the visible region under UV excitation. 52…”

“…This is principally due to the presence of Cu + ions that, unlike the Cu 2+ ions, are nonluminescent, and emit bright luminescence in the visible region under UV excitation. 52 After being exposed to the lowest applied dose of proton irradiation (3.3 × 10 3 Gy), the treated glass encountered a decrease in its PL intensity (Fig. 2, red curve).…”
