Doped Organic Electroluminescence from a Novel Rare Earth Complex Tb （3-metho） 3 phen

A novel rare earth complex Tb(3-metho)3phen was synthesized and characterized. The complex was doped into PVK to improve the conductivity and film-forming property of Tb(3-metho)3phen. A device with a structure of ITO/PVK∶Tb(3-metho)3phen /Al was fabricated to study the electroluminescent properties of Tb(3-metho)3phen. And the optoluminescent and AFM properties of this device were also studied, which proved the existence of energy transfer from PVK to Tb(3-metho)3phen. As a result, a pure green emission with sharp spectral band at 547.5 nm was observed.
