Method for preparing polymethylacrylic acid functionalized rare-earth polymer composite luminescent material

Abstract

The invention belongs to the field of rare-earth polymer composite luminescent materials and in particular relates to a method for preparing a polymethylacrylic acid functionalized rare-earth polymer composite luminescent material. A functional polymer is prepared through addition polymerization; a rare-earth ion is compounded to a polymer chain through a coordinate bond to prepare a rare-earth polymer compound; and the obtained compound is embedded in a Si-O network substrate by a sol-gel method. On the basis, in order to improve the optical performances of the material, an organic micromolecule is further introduced into the system to obtain the rare-earth polymer composite luminescent material with stable chemical and thermodynamic properties and characteristic fluorescence-emission. The experiment condition of the method is mild; the operability is strong; and the quality of the obtained product is stable.

Description

technical field [0001] The invention belongs to the technical field of preparation of rare earth polymer composite luminescent materials, and in particular relates to a preparation method of polymethacrylic acid functionalized rare earth polymer composite luminescent materials. Background technique [0002] With the rapid development of science and technology, people's requirements for the performance of materials are also continuously increasing. Traditional materials are increasingly unable to meet people's needs. In recent years, with the emergence and development of composite materials, these needs of people are being continuously met. The biggest advantage of composite materials is that it can combine the advantages of several different materials, which greatly expands the scope of application of materials in practice. [0003] Rare earth elements have a special electronic shell structure, so they exhibit excellent optical properties. my country is rich in rare e...

Problems solved by technology

Since the f-f transition of rare earth ions is forbidden, it shows very weak absorption in the visible and ultraviolet regions, which greatly affects its optical properties.

Although rare earth complexes can overcome this weakness to a certain extent, pure rare earth complexes often have the disadvantages of poor light and thermal stability, which limits their application in real life.
