Embodiment Construction

[0023] This embodiment is a rare earth terbium-based molecular crystalline green light material, and its chemical formula is: [Tb 2 (TATAB) 2 ·solvents]} n ,

[0024] Wherein TATAB is 2,4,6-tris[(p-carboxyphenyl)amino]-1,3,5-triazine anion ligand, solvents are solvent molecules, and n is a natural number from 1 to positive infinity;

[0025] The simplified structure of TATAB is as follows:

[0026]

[0027] The preparation method of a rare earth terbium-based molecular crystalline green light material of the present embodiment is as follows:

[0028] 100 mg of terbium chloride hexahydrate and 150 mg of 2,4,6-tris[(p-carboxyphenyl)amino]-1,3,5-triazine ligand were dissolved in 1500 mg of N,N-dimethylformamide, After that, the temperature is 120° C. for 48 hours, and a colorless bulk crystal is obtained, which is the rare earth terbium-based molecular crystalline green light material.

[0029] The rare earth terbium-based molecular crystalline green light material prepar...

Abstract

The invention relates to a rare earth terbium-based molecular crystalline green light material and a preparation method thereof, the chemical formula of the rare earth terbium-based molecular crystalline green light material is [Tb2 (TATAB) 2. Solvents]} n, TATAB is a 2, 4, 6-tri [(p-carboxylphenyl) amino]-1, 3, 5-triazine anion ligand, and solvents is a solvent molecule. The material is prepared through a solvothermal method, can emit 470-640 nm green light under excitation of 337 nm ultraviolet light, the green light CIE coordinate of the material is (0.2928, 0.6044) and is close to a saturated green light CIE coordinate, and the material can be used as a green light material, can realize temperature fluorescence sensing, has a wide temperature detection range (303-373 K), and is expected to be practically applied in the aspect of temperature sensing.

Description

technical field [0001] The invention relates to a rare earth terbium-based molecular crystalline green light material and a preparation method, and belongs to the technical field of molecular crystal materials. Background technique [0002] Temperature is an important physical parameter in the field of human life and natural science, so its accurate measurement is of great significance in science and human development. Traditional contact thermometers such as glass thermometers, thermocouples based on the Seebeck effect, and thermal resistance thermometers must be measured in contact. The applications in fluid systems and in vivo (tissues and even cells) are greatly limited. Compared to traditional contact thermometers, luminescence-based thermometer technology has unique characteristics including non-invasiveness, accuracy, and applicability under conditions of rapid motion and strong electromagnetic fields. Therefore, it is very necessary to develop and develop luminesce...
