摘要：

Powders La2O3 doped with 1 mol% Eu were prepared via a combustion route using different reducers (urea, glycine and citric acid). The structure and morphology were determined-with XRD and HRTEM measurement. The main emission positions centered at 626 nm for D-5(0) -> F-7(2) transition are observed. The variation of CT band with different reducers is observed. The intensity of D-5(0) -> F-7(1) transition centered at 626 nm with respect to that of D-5(0) -> F-7(1) transition is a function of the energy difference Delta E between the two CT band positions.
