Investigation of Eu 3 + luminescence intensification in Al 2 O 3 powders codoped with Tb 3 + and prepared by low-temperature direct combustion synthesis
The luminescence properties of Eu 3 + : Tb 3 + : Al 2 O 3 powders prepared by low-temperature direct combustion synthesis was investigated. It was observed that the presence of Tb 3 + ( 1.0 mol % ) modifies the dynamics of the radiative transition D 0 5 → F 2 7 of Eu 3 + ( 1.0 mol % ) and produces a...
