Borate and phosphate glasses possess many potential luminescence and optical applications. With their low melting point, they are one of the most often studied amorphous materials. In recent years these glasses, doped with transition metal oxides (TMO), gained much attention due to their tunable structural and thermal properties. Review of systems containing TMOs was presented. Additionally synthesis of binary MnO-P2O5 and MnO-B2O3 systems was presented. In this work xMnO-(100-x)P2O5 and xMnO-(100-x)B2O3 (where x = 40, 50 and 60 mol%) glasses have been synthesized and compared. Conventional melt-quenching technique has been used in both cases. Amorphous material has been obtained in two series of samples. Infrared spectroscopy studies (FTIR) shown some structural modifications in function of MnO content. It is proposed that MnO causes degradation of structural units of both phosphate and borate glasses. DSC studies presented different effect on Tg and melting temperature change in case of considered systems. Further, TMO affects differently the thermal stability ofsynthesized glasses.
