mol% and 10 y 20 mol% were prepared by melt quenching technique, with 30 minutes pre-
heating and 10 minutes for melting. The structural properties of prepared samples were
studied using Fourier Transform-Infrared spectroscopy. The glasses were mainly based on
PO2, BOP and BO3 unit. In order to obtain luminescence properties, another series of
sample at composition 20PbO-30ZnO-10B2O3-40P2O5 doped with Fe2+, Ti2+, Y2+ and …
