Analysis of emission of Eu3+ and Dy3+ doped Magnesium Boro-Tellurite (MBT) ceramics

Rare earth (RE) ions play an important role in the improvement of the optical properties of ceramics. Rare-earth ceramics are commonly used in display panels, fluorescent lamps and lasers. The luminescence properties of Magnesium Boro-Tellurite (MBT) Eu 3 + and Dy 3 + doped ceramics have not been re...

A series of xTeO 2 –(70 - x)B 2 O 3 –30MgO ceramics with 10 6 x 6 40 mol % doped with 1 mol % of Eu 3 + and Dy 3 + ions was prepared via the solid-state reaction method.
