Embodiment 1
[0068] This embodiment provides a white light OLED device, which includes an anode, a hole injection layer, a light emitting layer, an electron transport layer and a cathode which are sequentially stacked. Wherein, the light-emitting layer has a single-layer structure, and its material is 10-(3-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)-10H- Phenoxazine, the material of the anode is ITO, the material of the hole injection layer is TAPC, the material of the electron transport layer is TPBI, and the material of the cathode is Al.
[0069] The maximum luminance of the white OLED device of this embodiment is 1000cd / m 2 ~1100cd / m 2 ; The CIE coordinates when the lighting voltage is 3.5V and 8V are (0.29, 0.36), and the change of the CIE coordinates in the process from 5V to 10V is only (±0.01, ±0.01); the luminous uniformity is greater than 95%. The white light OLED device provided in this embodiment exhibits excellent luminous performance.
[0070] The manufacturing method of t...
Embodiment 2
[0081] In the description of Embodiment 2, the similarities with Embodiment 1 will not be repeated here, and only the differences with Embodiment 1 will be described. The difference between embodiment 2 and embodiment 1 is that the material of the cathode in the white light OLED device in this embodiment is Al; and the light-emitting layer is obtained by spin-coating.
[0082] Specifically, in step 3 in Example 1, first, use a 1mL syringe to extract 0.3mL-0.5mL PEDOT:PSS and evenly drop it on the Plassma-treated substrate, and then use a homogenizer at 3000r / min-4000r / min The speed of 30s to 40s for 30s to 40s, and then move the uniform spin-coated hole injection layer film to a hot table and bake it at 160°C for 8min to 10min to obtain a stable and uniform hole injection layer with a thickness of 20nm to 30nm; Then, weigh 30 mg of 10-(3-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)-10H-phenoxazine shown in the above formula 2-2 and place it in a 4mL Then measure 2mL of chlorobe...
Embodiment 3
[0085] In the description of Embodiment 3, the similarities with Embodiment 1 will not be repeated here, and only the differences with Embodiment 1 will be described. The difference between embodiment 3 and embodiment 1 is that the material of the cathode in the white light OLED device in this embodiment is Al; and the light-emitting layer is made by inkjet printing.
[0086] Specifically, in step 3 in the same embodiment 1, at first, put the Plassma-treated substrate on the inkjet printer, select a 4mL reagent bottle, measure 1mL PEDOT:PSS and add it to the reagent bottle, and then Measure 3mL of ethylene glycol into the reagent bottle, place the reagent bottle at a frequency of 99kHz and sonicate for 10min~15min to obtain the hole injection layer solution; then, use a 1mL syringe to draw 0.3mL~0.5mL of the hole injection layer solution Inject into the card holder, and then print a uniform hole injection layer along the strip-shaped ITO on the substrate, and then move the hol...
