Abstract
A new fluorescent Eu3+ polymer complex with the trivalent europium (Eu3+) ion directly bonded to a polymer chain was synthesized, and a new organic electroluminescent (EL) device in which it is used as the emitting layer was fabricated successfully for the first time. It was found that the EL and PL spectra of the device and its film were different from each other; for the former, the emission peaks lie at 595 nm and 657 nm, while it is at 618 nm for the latter. The difference between EL and PL was also discussed.Keywords
