N2 - Er3⁺-doped AlBaKMgAg phosphate glass was successfully synthesized via melt-quenching and comprehensively characterized for multifunctional applications. Structural analysis confirmed the amorphous nature with depolymerised Q⁰–Q2 phosphate units, while UV–Vis-NIR spectroscopy revealed characteristic Er3⁺ absorption bands (321–666 nm), confirming successful ion incorporation. The glass exhibited a 3.9 eV optical band gap and intense green emission under 380 nm excitation, alongside high microhardness and promising dielectric performance. Gamma-ray shielding studies demonstrated strong attenuation capabilities with high Zeff and Neff values. EPR analysis verified Er3⁺ ions in distorted octahedral coordination, while thermoluminescence revealed stable trapping centers at 196 °C and 348 °C, indicating potential for radiation dosimetry. These results collectively highlight the material's suitability for photonic, shielding, and dosimetric applications.
