Rare earth luminescent dye, fabric and preparation method thereof

The invention discloses a rare earth luminescent dye. The rare earth luminescent dye comprises a light-convertible dye and an ultraviolet curing agent, the light-convertible dye comprises an organic framework dye composite material coated with a rare earth luminescent material. The organic framework dye composite material in the coating layer comprises a compound of a covalent organic framework material and dye. According to the invention, the organic framework coating material and the disperse dye are creatively compounded to form an effect similar to that of a lampshade. And then the rare earth luminescent material is coated, so that the focusing effect of the rare earth luminescent material is improved, the emitted light is softer, and the light conversion and luminescence effects are realized. 本申请公开了一种稀土发光染料，包括可光转换染料和紫外光固化剂；可光转换染料包括有机骨架染料复合材料包覆稀土发光材料。包覆层中的有机骨架染料复合材料包括共价有机骨架材料和染料的复合物。本申请通过创新性地采用有机骨架包覆材料与分散染料进行复合，形成类似灯罩的效果。然后对稀土发光材料进行包覆，提高稀土发光材料的聚焦效果，让发光更加柔和，从而实现转光和发光效果。
