High-efficiency fluorescent organic light-emitting devices using a phosphorescent sensitizer

  title={High-efficiency fluorescent organic light-emitting devices using a phosphorescent sensitizer},
  author={Marc A. Baldo and Mark E. Thompson and Stephen R Forrest},
To obtain the maximum luminous efficiency from an organic material, it is necessary to harness both the spin-symmetric and anti-symmetric molecular excitations (bound electron–hole pairs, or excitons) that result from electrical pumping. This is possible if the material is phosphorescent, and high efficiencies have been observed in phosphorescent organic light-emitting devices. However, phosphorescence in organic molecules is rare at room temperature. The alternative radiative process of… CONTINUE READING
