Luminescence characteristic of a new novel coprecipitate rare earth complexes

The Tb3+ ion was introduced in the TbxEu1-x (BSA)(3) phen as a bridge to make the energy transfer process from ligand to the Eu3+ complex more efficient. The characteristics of the device used ThxEu1-x (BSA)(3) phen as the emission material with the different ratio of x were discussed. When x is 0.5, the device emits pure red color with the maximal brightness of 100 cd . m(-2) and has good commutation property. The role of the Tb3+ ion in the energy transfer process between the ligand and the Eu3+ ion and the mechanism of energy transfer process were also discussed.
