In this work, the optical and radiation-shielding characteristics of Sm3+-doped alkaline earth zinc borophosphate glasses with the chemical description 30ZnO-15B(2)O(3)-44P2O5-1Sm(2)O(3)-10AO [where A = Mg (MZBPS), Ca (C-ZBPS), Sr (S-ZBPS), and Ba (B-ZBPS)] were investigated. The mass attenuation coefficients (mu/rho) of the glasses were estimated using data generated from the FLUKA Monte Carlo code and from the NIST XCOM database. Optical parameters and neutron cross-sections were obtained using standard theoretical models. The mu/rho of M-ZBPS, C-ZBPS, S-ZBPS, and B-ZBPS varied in the range of 0.124-21.912 cm(2)/g, 0.024-22.564 cm(2)/g, 0.025-22.163 cm(2)/g, and 0.026-27.150 cm(2)/g, respectively. Also, the cross-section for fast neutron removal in M-ZBPS, C-ZBPS, S-ZBPS, and B-ZBPS was 0.0956 cm(-1), 0.0949 cm(-1), 0.0948 cm(-1), and 0.0953 cm(-1), respectively. The thermal neutron cross-section values were in the order M-ZBPS < C-ZBPS < S-ZBPS < B-ZBPS. The analysis of the optical parameters indicated that the optical density of the glasses increased as the atomic weight of the alkaline earth metal and glass density increased. The X-ZBPS glasses demonstrated good photon-shielding ability and optical properties, making them attractive for modern technical applications.
