Dysprosium rare earth-organic framework material as well as preparation method and application thereof

The invention discloses a dysprosium rare earth-organic framework material, the composition of the dysprosium rare earth-organic framework material is DyxLy (G) n, L is a tetracarboxylic acid organic ligand with different groups on a triphenyl skeleton, and G represents a solvent molecule coordinated with rare earth ions or in a crystal pore channel. The dysprosium rare earth-organic framework material is synthesized through a solvothermal method, the process is simple, the condition is mild, and the crystal form is good and controllable; the thermal coupling energy level based on Dy < 3 + > and the dual-luminescence intensity ratio based on the ligand and Dy < 3 + > in the rare earth organic framework material are effective means for temperature detection, so that the rare earth organic framework material has the advantages of excellent temperature detection performance, wide temperature measurement range, high relative sensitivity, low temperature resolution and good repeatability; mode adjustment of a norm
