Abstract

The invention discloses a flexible light-emitting device and a preparation method thereof. The device comprises a flexible polyimide / silver (PI / Ag) electrode substrate, namely a first electrode, a metal counter electrode, namely a second electrode, separated from the first electrode, and at least one zinc sulfide layer arranged between the first electrode and the second electrode. The invention also discloses a preparation method of the device. The PI / Ag electrode substrate is prepared by an all-solution method, other functional layers are prepared by a spin-coating process, the process is simple, the cost is low, and the flexibility of the device is high.

Description

technical field [0001] The invention belongs to the field of design and manufacture of electroluminescent devices, and specifically designs a flexible electroluminescent device using zinc sulfide material as a light-emitting layer material and a preparation method of the electroluminescent device by spin coating and the like. Background technique [0002] With the improvement of people's living standards and the diversification of environmental conditions, the diversified demand for luminescent lighting equipment is becoming stronger and stronger. Most of the light-emitting devices in the prior art are rigid light-emitting devices, which are not suitable for bending scenes, and the existing light-emitting devices occupy a large volume. In addition, the flexible light-emitting devices in the prior art use PET / ITO as electrodes, but the material has Certain flexibility, but limited flexibility, limited in many application scenarios. Contents of the invention [0003] In ord...
