AI Technical Summary

Technical Problem

Existing technologies struggle to prepare high-quality lead halide perovskite nanocrystalline films, resulting in the loss of their polarization luminescence properties on a macroscopic scale. There is a lack of simple and effective methods to achieve high polarization and stability.

Method used

By dispersing FAPbBr3 nanoparticles in a solvent and then drop-coating them onto a substrate for self-assembly, an ordered microstructure film can be formed. The arrangement and stacking of nanocrystals can be controlled, and the preparation method is simple and easy to adjust.

Benefits of technology

It achieves high polarization degree and long-term stability of polarized light emission characteristics, making it suitable for optoelectronic devices such as AR/VR displays, high-speed optical communication and advanced sensor imaging.

Abstract

The application belongs to the field of preparation of lead halide perovskite ordered microstructure, and particularly relates to an ordered microstructure film with polarized light emission characteristics and a preparation method thereof, wherein FAPbBr3 nanoparticles are dispersed in a solvent at a certain concentration, then dropped on a substrate and self-assembled to form the film. By adjusting the arrangement of the prepared perovskite nanoparticles, the nanoparticles are arranged in an oriented manner to form a micron-level ordered microstructure, and linearly polarized light and rotary light are emitted. The ordered microstructure prepared by the method has uniform size distribution, the preparation process is simple, the polarized light emitted has less energy consumption and higher efficient light path design compared with traditional linear polarizer optical devices, and the method has important significance for promoting the development of next-generation compact and efficient optoelectronic systems.
