Abstract

The invention provides a fluorescent composite material formed by compounding layered silicate and organic fluorescent molecules, and a preparation method thereof. The preparation method comprises the following steps: preparing layered silicate and organic fluorescent molecules, adding silicate into a fluorescent molecule solution, and treating to obtain the fluorescent composite material. The adsorption capacity of the composite material is calculated by measuring the residual content of the fluorescent molecules in a filtrate, the fluorescence performance of the obtained fluorescent composite material is improved compared with that of the fluorescent molecules, particularly, the fluorescence performance is improved to different extents after different minerals are compounded with the fluorescent molecules, and after the halloysite is compounded with rhodamine B, the fluorescence intensity is obviously improved.

Description

technical field [0001] The invention relates to a layered structure silicate fluorescent composite material and a preparation method thereof, belonging to the field of material chemistry. Background technique [0002] Organic fluorescent molecules are currently widely used in various fields such as chemistry and materials chemistry because of their advantages such as various types, rich colors, good adjustability, and high color purity. It has shown broad application prospects in multi-color display, lighting devices, etc., and has attracted much attention from the scientific and technological circles and industrial circles of various countries. [0003] Common organic fluorescent molecules include rhodamines, coumarins, quinacridones, etc. However, the mutual aggregation of organic fluorescent molecules can easily cause the shift, broadening or fluorescence quenching of the emission spectrum, thereby reducing the luminous efficiency and limiting its practical application. ...
