| Abstract: | When employing the conventional melt quenching technique for the preparation of Mn2+-doped glasses, it is observed that Mn2+ readily undergoes oxidation to Mn3+ during high-temperature melting. Typically, researchers incorporate reducing agents into the synthesized raw materials or utilize a reducing atmosphere when preparing samples to mitigate this phenomenon. In this study, a novel approach was proposed to suppress Mn2+ oxidation and enhance its luminescent properties. The zinc phosphoborate glasses based on 28.1P2O5–10.9B2O3–28.1ZnO (P–B–Zn) were prepared using the traditional melt quenching method. The effect of Cd2+ on the red emission of Mn2+ was studied by doping 2.9 mol% Mn2+ and changing the concentration of Cd2+ in the glasses. The analysis of photoluminescence emission (PL) spectroscopy and photoluminescence excitation (PLE) spectroscopy revealed a significant enhancement in the red emission resulting from the 4T1 (G) → 6A1 (S) transition of Mn2+ under 409 nm excitation after doping with Cd2+ ions. When the doping content of Cd2+ is 19 mol%, the luminescence intensity of Mn2+ reaches its maximum value, which is 4.24 times higher than that of undoped Cd2+. The results of the absorption and transmission spectra indicate a weakening of the 5Eg → 5T2g transition of Mn3+ and an increase in the transparency of the glasses. The significant reduction in the absorption peak of Mn3+ suggests that doping Cd2+ can effectively inhibit the oxidation of Mn2+ to Mn3+, as further confirmed by X-ray photoelectron spectroscopy (XPS) analysis.
