[0036] The method for preparing the above-mentioned organic electroluminescent device specifically includes the following steps:
[0037] 1. Rinse the glass with distilled water and ethanol, and soak it in isopropanol overnight.
[0038] 2. Prepare a conductive anode film on the glass cleaned in the above steps to obtain an anode conductive substrate, and then vapor-deposit sequentially on the anode conductive substrate to prepare a hole injection layer, a hole transport layer, a light-emitting layer, and an electron transport layer.
[0039] 3. Next, an electron injection layer is prepared on the electron transport layer. The electron injection layer is composed of a rubidium compound layer, a ternary doped layer and a rhenium compound layer.
[0040] First adopt thermal resistance evaporation described rubidium compound, its material is rubidium carbonate (Rb 2 CO 3 ), rubidium chloride (RbCl), rubidium nitrate (RbNO 3 ) or rubidium sulfate (Rb 2 SO 4 ), the thickness i...
