Rare earth composite fluorescent material taking carbonate as matrix and preparation method thereof

Abstract

The invention provides a rare earth composite fluorescent material taking carbonate as a matrix and a preparation method of the rare earth composite fluorescent material. According to the preparationmethod, europium ions are used as a luminous body; triphenyl phosphine oxide (TPPO) and 2-thiophenyltrifluoroacetone (TTA) are taken as organic ligands; calcium carbonate is taken as a matrix; an europium complex composite fluorescent material is prepared under set conditions, and the obtained composite fluorescent material is characterized. The cost of the fluorescent material is reduced, and theprepared material is long in service life, high in quantum yield, high in fluorescence intensity and good in fluorescence performance.

AI Technical Summary

Problems solved by technology

[0005] Fluorescent materials of rare earth complexes have the advantages of unique molecular structure, photoluminescence mechanism, strong fluorescence and good monochromaticity, and are applied in many fields such as industry, agriculture, biology, etc., but their light and thermal stability are slightly poor. Moreover, in recent years, because rare earths have gradually been used as strategic resources, more and more attention has been paid to them. Therefore, the price of rare earths has continued to rise, and it is difficult to recycle rare earth complexes after use, which has led to greater restrictions on the application of rare earth complexes in many aspects limitations
