Embodiment 2

[0092] see Figure 10 , Figure 10It is a schematic flowchart of the second structure of the preparation method of the control layer provided in the embodiment of the present application.

[0093] It should be noted that the difference between embodiment 2 and embodiment 1 is:

[0094] read on image 3 . Change the small voltage to a large voltage, that is, the large voltage is the second voltage; the small electric field is changed to a large electric field, that is, the large electric field is the second electric field, and the control layer 10 is formed, and the nanoparticles 100 are closely packed, that is, the nanoparticles 100 are in the Under the action of the large electric field, the refractive index of the control layer 10 changes from 1.5 to 2.4. .

[0095] Specifically, a large voltage is applied to the first electrode and the second electrode to form a large electric field, and the nanoparticles 100 are composed of CdSe / ZnS and the ligand as polyethylene glyc...

Abstract

The invention discloses a regulation and control layer, a preparation method thereof and a photoelectric device. The material of the regulation and control layer comprises charged or electrically polarizable nanoparticles. In the application, the regulation and control layer is formed by the nanoparticles which are charged or can be electrically polarized in the solvent, so that the refractive index of the regulation and control layer can be regulated and controlled by regulating and controlling the density of the nanoparticles, and the performance of the device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a control layer, a preparation method and a photoelectric device. Background technique [0002] Nanomaterials refer to the size of their structural units ranging from 1 nanometer to 100 nanometers. It has surface effect, small size effect and macroscopic quantum tunneling effect. When people subdivide a macroscopic object into ultrafine particles (nanoscale), it will show many strange properties, namely its optical, thermal, electrical, magnetic, mechanical and chemical properties and phases of bulk solids. will be significantly different. Therefore, it is widely used in many fields. [0003] At present, the film layer formed by nanomaterials is usually formed by spin coating, and the film layer formed by spin coating has a fixed and non-adjustable refractive index, so that the film layer cannot meet the requirements of the device's refractive index well. thereby a...
