Rare-earth ions Tb3+ and La3+ 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 detail and it was found that the device using La0.5Eu0.5 (BSA)3phen as the emission material had better monochromatic characteristics with the maximal brightness of 102cd/m2 and the colour coordinates x = 0.55 and y ＝ 0.36.
