摘要：

The luminescence properties of Eu3+:Tb3+:Al2O3 powders prepared by low-temperature direct combustion synthesis was investigated. It was observed that the presence of Tb3+ (1.0 mol %) modifies the dynamics of the radiative transition D-5(0)-> F-7(2) of Eu3+ (1.0 mol %) and produces an enhancement of the luminescence intensity by one order of magnitude.
