This document summarizes a study on the optical properties of manganese ion (Mn2+)-doped cadmium aluminum fluoro lead borate glass. The glass was prepared with the composition 49.5B2O3-10PbO-30CdO-10AlF3 doped with 0.5% Mn2+. Optical absorption spectroscopy showed a broad absorption band at 473 nm, confirming the presence of Mn2+ ions. Photoluminescence spectroscopy revealed a red emission at 618 nm under excitation at 467 nm, attributed to the 4T1g(G) → 6A1g(S) transition of Mn2+ ions in an octahedral environment. The
