Embodiment 1

[0257] Embodiment 1: green organic electroluminescent device

[0258] Use the following methods to fabricate green organic electroluminescent devices:

[0259] The anode was prepared by the following process: the thickness of ITO was The ITO substrate was cut into a size of 40mm (length) × 40mm (width) × 0.7mm (thickness), and it was prepared into an experimental substrate with cathode, anode and insulating layer patterns by photolithography process, and ultraviolet ozone and o 2 :N 2 Plasma is used for surface treatment to increase the work function of the anode, and organic solvents can be used to clean the surface of the ITO substrate to remove impurities and oil on the surface of the ITO substrate. It should be noted that the ITO substrate can also be cut into other sizes according to actual needs, and there is no special limitation on the size of the ITO substrate in this application.

[0260] F4-TCNQ was vacuum evaporated on the experimental substrate (anode) to for...
