Abstract
  • Numerous investigations on organic electroluminescent (EL) devices based on organic dyes and polymers, being the latter more easily processable, have been extensively reported; among them, those where lanthanide complexes are employed as dopant in polymer host matrix are of great interest. In a previous work we obtained, for the first time, tunable multicolor EL emission from dispersion of a Eu3+ complex in the electroluminescent poly(9,9-dioctylfluorene) (PFO). The result has been reached by designing a complex whose ligand, with long alkyl chains, increases site isolation of Eu3+ ion and reduces the strong quenching effect due to back-transfer typical of Eu3+ complex:PFO blends. Spin-coated devices showed blue and red contemporary emission, (see Fig.1) with a maximum external quantum efficiency as high as 1%. (literal)
