preparation example Construction
[0137] Specifically, the preparation method of the organic electroluminescent device of the present invention comprises the following steps:
[0138] 1. Ultrasonically treat the glass plate coated with the anode material in a commercial cleaning agent, rinse in deionized water, ultrasonically degrease in acetone: ethanol mixed solvent, bake in a clean environment until the water is completely removed, and use ultraviolet light Light and ozone cleaning, and bombardment of the surface with a beam of low-energy cations;
[0139] 2. Put the above-mentioned glass plate with anode in the vacuum chamber, and evacuate to 1×10 -5 ~9×10 -3 Pa, vacuum evaporating a hole injection material on the anode layer film to form a hole injection layer, and the evaporation rate is 0.1-0.5nm / s;
[0140] 3. Vacuum evaporate the hole transport material on the hole injection layer to form the hole transport layer, the evaporation rate is 0.1-0.5nm / s,
[0141] 4. On the hole transport layer, the ele...
