Embodiment 1
[0089] The glass plate coated with the ITO transparent conductive layer is ultrasonically treated in a commercial cleaning agent, rinsed in deionized water, ultrasonically degreased in acetone-ethanol mixed solvent, baked in a clean environment until the water is completely removed, and then cleaned with ultraviolet light. Light and ozone cleaning, and bombardment of the surface with a beam of low-energy cations;
[0090] Place the above-mentioned glass substrate with the anode in a vacuum chamber, and evacuate to less than 10 -5 Torr, HT-11 was vacuum evaporated on the above anode layer as a hole injection layer, the evaporation rate was 0.1nm / s, and the evaporation film thickness was 10nm;
[0091] On the hole injection layer, HT-5 material was vacuum evaporated as the hole transport layer, the evaporation rate was 0.1nm / s, and the total film thickness was 80nm;
[0092] The light-emitting layer of the device is vacuum-evaporated on the hole transport layer. The light-emitt...
