Description

Technical Field

[0001] This invention relates to the field of luminescent materials, specifically to an organic-inorganic hybrid antimony halide, its preparation method, and its application. Background Technology

[0002] Organic-inorganic hybrid antimony halides (OISbHs), as an emerging class of optoelectronic functional materials, have attracted widespread attention in the field of optoelectronic materials in recent years due to their excellent optical properties, solution processability, low toxicity, and structural tunability, becoming one of the research hotspots. Compared with traditional all-inorganic antimony-based luminescent materials and antimony-doped luminescent materials, OISbHs, through the introduction of functionalized organic cations for structural modification and regulation, have not only successfully constructed diverse low-dimensional crystal structures such as zero-dimensional, one-dimensional, and two-dimensional, but also endowed the materials with unique self-trapped exciton luminescence mechanisms, ultra-large Stokes shifts, and excellent environmental stability, effectively making up for the shortcomings of traditional antimony-based materials in terms of structural tunability and stability.

[0003] Ions themselves possess a wide range of luminescence properties, and their emission wavelength can be flexibly adjusted through precise control of the chemical environment, such as ligand selection, crystal structure regulation, and doping concentration optimization, to achieve full-spectrum luminescence from the visible to near-infrared regions, providing a foundation for their adaptability in various optoelectronic applications. Based on this, existing technologies, through the functionalization design of organic cations and the spatial structure regulation of antimony halide polyhedra, can obtain OISbHs materials with high-efficiency photoluminescence, high-energy X-ray irradiation luminescence, and circularly polarized luminescence properties, demonstrating great application potential in fields such as LED lighting displays and fluorescence sensing.

[0004] However, the limited luminescence bandwidth and lack of dynamic color gamut control of OISbHs significantly restrict their application scenarios. Furthermore, existing OISbHs preparation methods mostly rely on liquid-phase reaction systems, such as solvothermal methods and solution evaporation methods. These methods all require an additional liquid reaction environment and the introduction of auxiliary materials such as organic solvents, reaction media, or catalysts. This not only increases raw material costs and the difficulty of subsequent separation and purification but may also affect the photoelectric properties of the material due to solvent residues. Simultaneously, some liquid-phase preparation processes have stringent requirements for reaction temperature, pressure, and atmosphere, necessitating complex experimental setups such as high-pressure reactors and precision temperature control equipment. This results in cumbersome processes, high operational difficulty, and low production efficiency, making it difficult to meet the needs of industrial-scale preparation. Summary of the Invention
