Effect of P2O5 content on spectroscopic properties of Eu-doped antimony-germanate glasses

In our work we focused on possibility of obtaining phosphate nano-phase structures in antimony-germanate glasses doped with europium ions. The molar composition of 50[Sb2O3 - (100-x)GeO2] – 50(SiO2 - Al2O3 - Na2O) - x P2O5 glass-ceramic (GC) system doped with 0.5mol% Eu2O3 was used for the fabrication of active core of double clad optical fiber (DCF). In order to optimize glass-ceramic system the influence of phosphate concentration (up to 5mol%) on structural and luminescence properties have been investigated.
