| abstract |
The invention relates to a time-resolved fluorescent material of a europium complex and a preparation method thereof, and belongs to the technical field of fluorescent materials. Its molecular formula is Eu(L1) 3 (L2) n ; wherein, L1 is a β-diketone ligand, and L2 is a cooperative ligand; n is 1 or 2; the cooperative ligand is triphenylphosphine oxide, 1 , 10-phenanthroline and one or more of 3,4,7,8-tetramethyl-1,10-phenanthroline. The time-resolved fluorescent material of the europium complex of the present invention has strong red fluorescence and good time-resolved characteristics under the irradiation of 365 nm ultraviolet laser, and can be used for time-resolved fluorescent microsphere dyeing, and can also be used as time-resolved fluorescent material. It has broad application prospects in medical clinical examination, immunochromatography and other fields. |
