Embodiment 1

[0028] Preparation of neodymium perchlorate solution: Weigh 10.00g of neodymium oxide, add 45mL of perchloric acid with a volume ratio of 1:1, filter out insoluble matter, set the volume to 250mL, and calibrate its concentration with a calibrated EDTA standard solution; The concentration of neodymium acid solution is 0.5M.

[0029] Preparation of the complex: react the above neodymium perchlorate solution at 60°C for 5h, then add glutamic acid at a molar ratio of neodymium:glutamic acid=1:4, adjust the pH value to 5 with alkaline solution, and then react at 60°C for 3h , and then add imidazole, the molar ratio of neodymium:imidazole=1:1, after reacting at 60°C for 3 hours, crystals were obtained after standing for a period of time.

[0030] Determination of the complex: Take the single crystal of the complex obtained above, and use the following method to determine its unit cell. The crystallographic data of the complex are collected with a BrukerSmart-1000CCD single crystal d...

Embodiment 2

[0034] Substitute samarium oxide for neodymium oxide, and other steps are the same as in Example 1. The crystallographic data of the complexes are shown in Table 1 and Table 2. Its crystal is monoclinic system, the space group is C 2 / c , the cell parameters are Z=4.

[0035] Fluorescence spectrum: as Figure 5 As shown, the crystal can produce relatively strong fluorescence at about 387nm.

Embodiment 3

[0037] Lanthanum oxide, cerium oxide, praseodymium oxide, holmium oxide, europium oxide, erbium oxide, and lutetium oxide were used instead of neodymium oxide, and other steps were the same as in Example 1 to obtain the corresponding rare earth amino acid imidazole single crystal complex. Its crystal is monoclinic system, the space group is C 2 / c , Z=4.

[0038] Example 3

[0039] First, react neodymium oxide with perchloric acid to prepare 1M neodymium perchlorate solution, add glutamic acid at 80°C for 1 hour, molar ratio neodymium:glutamic acid=1:8, adjust pH=8 with alkaline solution React at 80°C for 1 hour, then add imidazole, the molar ratio of neodymium:imidazole=1:4, react at 80°C for 1 hour, and let it stand for a period of time to obtain crystals. Other steps are the same as in Example 1.

Abstract

The invention discloses an energy-containing fluorescent material rare earth-glutamic acid-imidazole single crystal complex and a preparation method thereof. The complex is prepared from rare earth metal, glutamic acid, imidazole and perchloric acid, the molecular formula of the complex is Ln(Gly)4IM.(ClO4)4 (Ln: Nd, Sm, La, Ce, Pr, Ho, Eu, Er, Lu). The preparation process includes the steps that rare earth oxide and perchloric acid react so that a perchloric acid and rare earth solution can be prepared, glutamic acid is added for reaction, reaction is performed after the pH value is adjusted through an alkaline solution, and crystals are obtained after imidazole is added for reaction and reactants are placed for a period of time. The technology is easy and convenient to perform, ligand selection is scientific, the synthesized rare earth amino acid single crystal complex is clear and novel in structure, and meanwhile the single crystal structure provides a new basic scientific basis for a crystal database. The complex can release a large number of energy in the decomposing process and is a potential energy-containing material. The complex has high fluorescent performance.

Description

technical field [0001] The invention relates to an energy-containing fluorescent material rare earth metal amino acid imidazole single crystal complex, in particular to a rare earth-glutamic acid-imidazole single crystal complex and a preparation method thereof; it belongs to the technical field of material preparation. Background technique [0002] Amino acids are a class of biological ligands that exist in large quantities in living organisms. They are the basic structural units of proteins, enzymes, etc., and are closely related to the physiological activities of the human body. With the continuous expansion of the application of rare earths in agriculture, medicine and biomolecular research, rare earths widely enter the environment and enter the organism through various channels. Rare earth has many biochemical functions, and the biological effects and biochemical changes it causes are various. It can inhibit various effects in organisms, affect the biological activity o...
