Description

technical field [0001] The invention relates to the technical field of preparation of luminescent materials, in particular to acridinium complex crystals, doped crystal luminescent materials and their preparation methods and applications. Background technique [0002] Organic light-emitting functional materials have attracted much attention due to their applications in optical waveguides, sensors, and optoelectronic devices, as well as their easily adjustable physical and chemical properties. Compared with pure inorganic materials, organic light-emitting functional materials usually have the advantages of easy structure adjustment and simple processing. However, organic light-emitting functional materials have poor thermal / optical stability due to low crystallinity, which affects their wide application in light-emitting devices. [0003] Acridine is an important class of photoelectric functional materials. The lower crystallinity directly affects the physical and chemical s...
