Embodiment Construction

[0028] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0029] see figure 1 , the invention provides a kind of preparation method of perovskite ink for inkjet printing, comprises the steps:

[0030] Step 1, providing a perovskite material and a solvent, and dispersing the perovskite material in the solvent to obtain a perovskite solution.

[0031] Specifically, the perovskite material is an organic-inorganic doped perovskite material, and the general structural formula of the organic-inorganic doped perovskite material is CH 3 NH 3 wxya 3 , wherein X=Cl, Br, or I. Through the selection of the halogen anion X in the perovskite material, the adjustment of different light colors can be realized.

[0032] Preferably, the perovskite material has a quantum dot size to have better luminescence perfor...

Abstract

The invention provides a perovskite ink for ink-jet printing and a preparation method of the perovskite ink. The preparation method of the perovskite ink for ink-jet printing has a simple preparation process; and the prepared perovskite ink for ink-jet printing has certain viscosity, surface tension and volatilization performance, and can meet the requirement on the preparation process of ink-jet printing to realize an ink-jet printing mode of a perovskite luminescent layer. The perovskite ink for ink-jet printing is prepared by adopting the method, can meet the requirement on the preparation process of ink-jet printing, and realizes the ink-jet printing mode of the perovskite luminescent layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a perovskite ink for inkjet printing and a preparation method thereof. Background technique [0002] Take ABX 3 The perovskite material with the basic chemical formula is calcium titanate (CaTiO), which was first found in perovskite 3 ) compound named after it. The perovskite structure is characterized by the common top connection of X octahedrons centered on B-site cations and embedded in tetragons with A-site ions as vertices. The A and B cations can be occupied by a single ion or multiple ions. According to the types of A and B cations and their ionic radii, perovskite materials with different microstructure characteristics and ever-changing physical properties can be constructed. [0003] The structure and physical properties of organic-inorganic hybrid perovskite (Organic / Inorganic Hybrid Perovskite, OIHP) materials were first reported by Weber (Naturforsch.1978,33b,1443...
