Structural and luminescence properties of Eu3+ and Dy3+-doped magnesium boro-tellurite ceramics
Boro-tellurite ceramics with the composition of 60B2O3-10TeO2-30MgO-1Eu2O3-1Dy2O3 in mol % were prepared by solid-state reaction method. The samples were characterized by x-ray diffraction (XRD), photoluminescence (PL) and FTIR spectroscopy. The XRD studies have revealed the presence of MgTe2O5 and...

Boro-tellurite ceramics with the composition of 60B2O3-10TeO2-30MgO-1Eu2O3-1Dy2O3 in mol % were prepared by solid-state reaction method.

The XRD studies have revealed the presence of MgTe2O5 and MgB6O10.7H2O crystalline as the major and minor phases in these samples. The FTIR spectra reveal the presence of B-O vibrations of B-O-B, BO3 and BO4 bridging oxygen and Te-O stretching modes of Te2O, TeO3 and TeO4 units in the prepared ceramics.
