Example Embodiment

[0095] Example 1

[0096] The 1.0mg median diameter D 50 600nm TiO 2 The particles were dissolved in 10 mL of 1-methoxy-2-propanol, thereby obtaining a white paste-like dispersion. And the dispersion was doped in 5mL 0.4mg / ml sodium alginate aqueous solution, and then it was coated on the cleaned glass substrate by spin coating method, and dried into a film with a thickness of 15μm at room temperature. Where multiple coatings make TiO 2 The particles are located on top of the sodium alginate.

[0097] 1mL of 1mg / ml silver nanowires (60-120nm in diameter and 10-20μm in length, purchased from Nanjing Xianfeng Nanomaterials Technology Co., Ltd.) in ethanol were coated on sodium alginate by spin coating. Dried into a film with a thickness of 200nm at room temperature;

[0098] Stick a clean and flat glass cover sheet on the prepared silver nanowire film, exhaust the air between the glass cover sheet and the silver nanowires, and apply a pressure of 12 MPa on the glass cover sheet to co...

Example Embodiment

[0101] Example 2-6

[0102] The transparent electrode was prepared in the same method as in Example 1, except that 1 mL of the dispersion of silver nanowires in ethanol was coated on the sodium alginate at the concentration shown in Examples 2-6 in Table 3.

Example Embodiment

[0103] Example 7

[0104] A transparent electrode was prepared in the same manner as in Example 5, except that 1.0 mg TiO 2 The particles are doped with 5mg aliphatic epoxy resin UVR-6128 (epoxy equivalent of 190-210g / mol, purchased from Xinjing Chemical Co., Ltd.) instead of sodium alginate.

Abstract

The invention relates to a transparent electrode, which comprises a substrate material and metal nanowires contained in the substrate material, wherein the substrate material is doped with scattering particles. The invention further relates to an organic electroluminescent device, which is sequentially provided with a substrate, a first electrode, an organic light-emitting functional layer and a second electrode from bottom to top, wherein the first electrode adjacent to the substrate is a transparent electrode, the transparent electrode includes a substrate material and metal nanowires contained in the substrate material, and the substrate material is doped with scattering particles.

Description

technical field [0001] The invention relates to the technical field of optoelectronic devices, in particular to a transparent electrode and an organic electroluminescence device comprising the same. Background technique [0002] An organic electroluminescence device includes a cathode, an anode, and a multilayer organic material layer disposed between the cathode and the anode, which includes a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like. Wherein, the light generated by the organic material layer is emitted through the transparent electrode. Organic electroluminescence devices can generally be classified into top emission type, bottom emission type and double-side emission type. In a top-emitting or bottom-emitting device, one of the two electrodes needs to be a transparent electrode; in a double-sided emitting device, both electrodes need to be transparent electrodes.
