Organic light emitting diode adopting minim metal doped organic receptor film

Using one kind of receptor trace metal doped organic thin organic light emitting diode, comprising: a substrate; a positive electrode, the positive electrode is deposited on the substrate, for injecting holes; a hole injection organic layer, the organic hole injecting layer was deposited on the positive electrode, the positive electrode for receiving from the injection holes; an organic hole transport layer, the organic hole transporting layer deposited on the organic hole injection layer, and for receiving transmissions from the organic hole injection layer hole; an organic light emitting layer, the organic light-emitting layer is deposited on the organic hole transport layer for emitting light; an organic electron injection layer, the electron injecting organic layer is deposited on the organic light emitting layer for the organic light-emitting layer transporting electrons; a cathode that is deposited on the organic electron injection layer for injecting electrons.
