The invention provides functional rare earth complex long-life fluorescent dye, a synthetic method and an application thereof; the synthetic method prepares the long-life fluorescent rare earth complex with thenoyltrifluoroaceton, 5-amino-1, 10-o-phenanthroline serving as ligands. The synthetic method is convenient, has long fluorescent life and active group amino group and very high application value.

The invention relates to a preparation method of red light emitting fluorescent powder. By aiming at the conditions of difficult film forming of red light fluorescent powder and poor ultraviolet light resistant performance, 2-thenoyltrifluoroacetone-phenanthroline-methacrylic acid-europium and (4-vinyl phenyl) trimethoxy silane is used as raw materials to prepare the red light emitting fluorescent powder through solution preparation, polymerization reaction, washing, suction filtration, vacuum freeze drying, grinding and screening. The preparation method has the advantages that the process is advanced; the data is precise, full and accurate; the prepared powder body material has high precision and good purity; the purity reaches 9.2 percent; the powder body particle diameter is less than or equal to 800nm; the chromaticity coordinate X is 0.625; Y is 0.308; red light is emitted out; the materials can be matched with blue and green luminous materials to be prepared into white light emitting light emitting diodes; the preparation method belongs to an advanced red light emitting fluorescent powder preparation method.
