Abstract

New glass compositions in the system 1 - x(SbPO4-ZnO-PbO)-xMnO (with 0 <= x <= 20 in mol%) were prepared by melt-quenching methodology. Thermal, structural and optical properties of the new glasses were systematically studied by means of differential scanning calorimetry (DSC), UV-Vis and Raman spectroscopy, fluorescence and electronic paramagnetic resonance (EPR). The addition of MnO increases the thermal stability of the glasses with Tx - Tg close to 140 degrees C for higher Mn contents. EPR measurements show that Mn2+ ions are in octahedral arrangement which is in agreement with UV-Vis and luminescence results. Samples present red luminescence when excited with 408 nm source. (AU)
