1. An organic light emitting device comprising:

  • a first conductive layer;

    a layer of first carrier transporting and second carrier blocking material positioned on the first conductive layer;

    a layer of organometallic material positioned on the layer of first carrier transporting and second carrier blocking material and having the following general formula;

    ##STR4## where;

    M2 is a divalent metal ion, andR1 to R8 represent substitution possibilities at each position and each represent hydrogen or hydrocarbon groups or functional groups;

    a layer of second carrier transporting and first carrier blocking material positioned on the layer of organometallic material; and

    a second conductive layer positioned on the layer of second carrier transporting and first carrier blocking materials.
