Photoluminescence characteristic of magnesium Boro-Tellurite doped Eu3+ Ceramic
The series samples of xTeO2-(70-x)B2O3-30MgO with 0≤x≤30 mol% have been prepared via the solid-state reaction method. The composition sample of 30TeO2-40B2O3-30MgO were chosen as a doped sample in the composition of 100-y(30TeO2-40B2O3-30MgO)-yEu3+ with 0.2≤y≤2 mol% and were heated at 750oC. The XRD...

The series samples of xTeO2-(70-x)B2O3-30MgO with 0≤x≤30 mol% have been prepared via the solid-state reaction method. The composition sample of 30TeO2-40B2O3-30MgO were chosen as a doped sample in the composition of 100-y(30TeO2-40B2O3-30MgO)-yEu3+ with 0.2≤y≤2 mol% and were heated at 750oC. The XRD results showed that the major phase was Mg(Te2O5) while MgO(B2O3)2, MgTe6O13, Mg2(B2O5) and MgB4O7 was observed as a minor phase. The small phase of EuB2O4 and Eu2Te4O11 were detected by XRD when the composition of 30TeO2-40B2O3-30MgO were doped with 1.5% of Eu3+. The EDX analysis of 30TeO2-40B2O3-30MgO doped with 1.5% Eu3+ sample was confirmed the presence of boron (B), magnesium (Mg), tellurium (Te), oxygen (O) and europium (Eu) elements.
