Abstract
We present the foundations of our arguments to enhance the quantum eff iciency of organic light-emitting diodes prepared by vapor deposition of 8-tris-hydroxyquinoline aluminium. By ion beam assisted deposition (LEAD) realized with 100 eV Iodine ions, we enhance by a factor 10 the quantum efficiency; we attribute this beneficial effect to the densif ication of the layer in the vicinity of the recombination area where o xygen diffusion is then limited.
