Abstract： Rare-earth ions Tb3+ ion and La3+ ion were used as a bridge to improve the energy transfer from the polymer to an Eu complex. The material Tb(La 0.5Eu0.5(BSA)3phen was synthesized and used as the emission layer in the device: ITO/PVK:Tb(La)0.5Eu0.5(BSA)3phen/Alq/Al. The two device were compared in details and it was found that the device used La0.5Eu0.5(BSA)3phen as the emission material had better Monochromatic characteristics with the maximal brightness of 102 cd/m2 and the colour coordinates x = 0.55 and y = 0.36.
