At present, the multiferroic materials composed of rare earth elements are mainly inorganic substances, such as rare earth manganese oxides (such as TbMnO 3 or TbMn 2 o 5 ) and rare earth iron oxides (such as Tb 3 Fe 5 o 12 ), due to the strong magnetoelectric coupling effect, it is one of the focuses of multiferroic materials research, but the research on inorganic-organic complex multiferroic materials containing rare earth elements is still blank

Abstract

The invention relates to a bimetallic crocic acid complex and a preparation method thereof. The bimetallic crocic acid complex has a chemical formula of [TbK(C5O5)2(H2O)6].2H2O and C5O5<2-> is a crocic acid anion. The preparation method of the bimetallic crocic acid complex comprises respectively dissolving crocic acid, TbCl3 and KOH in water, mixing the three solutions, carrying out stirring, standing the mixture at a room temperature for 3 days so that saffron yellow blocky crystals are precipitated, carrying out filtration and collecting the product. The complex contains a one-dimensional chain-type metal unit and antiferromagnetc interaction is formed between metal ions. The complex crystallizes in a polar space group and has ferroelectricity at a room temperature. The solid complex is stimulated by light with wavelength of 372nm and the sample can emit strong fluorescence. Therefore, the bimetallic crocic acid complex has antiferromagnetism, ferroelectricity and fluorescent properties and is a latent photoelectromagnetic multifunctional material.

Description

technical field [0001] The present invention relates to metal complexes, in particular to a bimetallic complex containing potassium and terbium, which specifically belongs to a complex with opto-electromagnetic properties based on mixed ions of potassium (I) and terbium (III) and croconic acid and its preparation method. Background technique [0002] Among the multifunctional materials based on the expansion of molecular materials, multiferroic materials that combine magnetism and ferroelectricity are the essence of many production technologies at present, and have important theoretical significance and potential application value. Ferrous materials have gradually entered people's sight in recent years. Because it has the advantages of both inorganic multiferroic materials and organic multiferroic materials, it is a multifunctional material with multiple bistable properties, so it has received more and more research work. attention. At present, the multiferroic materials c...
