ABSTRACT Glasses of the MnOx · (P2O5)40 · (ZnO)60−x system were prepared by the melt-quenching technique and thermally treated for 2 h at 650°C. To describe the influence of thermal treatment on zinc phosphate glass matrix doped with manganese ions, X-ray diffraction and infrared spectroscopy were used. The X-ray diffraction patterns revealed that the degree of crystallinity gradually decreased with increasing MnO content in the samples up to 5 mol% of MnO2. The manganese ions were also shown to be captured in the vitreous phase. The infrared spectra confirmed that the glass network underwent changes following thermal treatment. The spectra of thermally treated samples contained new peaks and the infrared bands become narrower compared to those of the untreated samples.
