The invention discloses a Eu/Zr-MOF fluorescent material with blue and red double emission and the application of the fluorescence ratio detection thereof. The material is prepared by the following steps: 1. Put the Eu/Zr molar ratio into the beaker 1 1:9～5:5, add europium salt and zirconium salt in turn, and then add DMF and glacial acetic acid as solvents according to the molar ratio of the total amount of metal ions to the solvent amount of 1:200～400:1, and stir to form a uniform Mix the solution; 2. Add DMF and NH 2 -BDC to the beaker 2 in a molar ratio of 200-400:1 and stir evenly, then mix the obtained solution with the solution in the beaker 1; 3. Transfer the above mixed solution into In the polytetrafluoroethylene liner of the hydrothermal kettle, place the hydrothermal kettle in an oven for hydrothermal reaction, and then naturally cool the hydrothermal kettle to room temperature; 4. Filter, wash and dry the product obtained from the above reaction to obtain light yellow powder sample. |
