摘要
By inserting a thin Gd(AcA)(3)phen layer in the electroluminescent devices ITO/Alq/Al and ITO/TPD/Eu(DBM)(3)phen/Alq/Al, the quantum efficiency is increased in both devices and the emission color of the second device is changed, These results are supposed to be due to the carrier-blocking effect of the thin Gd(AcA)(3)phen layer which changes the distribution of electrons and holes in the devices, (C) 1997 Elsevier Science S.A.
