Influence of gamma irradiation on physical, structural, and optical properties of Dy3+ doped barium bismuth borate sodium glasses

Barium bismuth borate sodium (BBBNDy) glasses doped with Dy<sub>2</sub>O<sub>3</sub> (0-0.8 mol%, x = 0.2 mol%) were prepared via the melt quenching approach and examined under gamma irradiation. XRD confirmed the amorphous nature, while density measurements (4.3387-4.4743 g/cm<sup>3</sup>) revealed composition and irradiation-dependent variations. FTIR and Raman studies indicated Dy<sub>2</sub>O<sub>3</sub>-induced network modification through BO<sub>3</sub>/BO<sub>4</sub> and BiO<sub>3</sub>/BiO<sub>6</sub> units, with minimal structural degradation under irradiation. Optical studies revealed tunable band gaps and low Urbach energies (0.1752-0.2266 eV) reflecting good structural order. Photoluminescence spectra exhibited a strong yellow emission at 575 nm (<sup>4</sup>F<sub>9/2</sub> → <sup>6</sup>H<sub>13/2</sub>), with optimal intensity for BBBNDy3 glass. Gamma irradiation induced PL quenching at 575 nm, with intensity reduced by to 66.6% at 5 kGy and 87.2% at 15 kGy; still, Dy<sup>3+</sup> emission remains detectable. These results highlight the dual role of Dy<sup>3+</sup> ions as structural stabilisers and efficient luminescent activators, identifying BBBNDy3 glasses as a strong candidate for photonic devices operating in radiation environments.

Abstract

Barium bismuth borate sodium (BBBNDy) glasses doped with Dy<sub>2</sub>O<sub>3</sub> (0-0.8 mol%, x = 0.2 mol%) were prepared via the melt quenching approach and examined under gamma irradiation. XRD confirmed the amorphous nature, while density measurements (4.3387-4.4743 g/cm<sup>3</sup>) revealed composition and irradiation-dependent variations. FTIR and Raman studies indicated Dy<sub>2</sub>O<sub>3</sub>-induced network modification through BO<sub>3</sub>/BO<sub>4</sub> and BiO<sub>3</sub>/BiO<sub>6</sub> units, with minimal structural degradation under irradiation. Optical studies revealed tunable band gaps and low Urbach energies (0.1752-0.2266 eV) reflecting good structural order. Photoluminescence spectra exhibited a strong yellow emission at 575 nm (<sup>4</sup>F<sub>9/2</sub> → <sup>6</sup>H<sub>13/2</sub>), with optimal intensity for BBBNDy3 glass. Gamma irradiation induced PL quenching at 575 nm, with intensity reduced by to 66.6% at 5 kGy and 87.2% at 15 kGy; still, Dy<sup>3+</sup> emission remains detectable. These results highlight the dual role of Dy<sup>3+</sup> ions as structural stabilisers and efficient luminescent activators, identifying BBBNDy3 glasses as a strong candidate for photonic devices operating in radiation environments.
