Embodiment 1

[0018] A, will 1.241G BA (NO 3 ) 2 Soluble in 20 ml of water to get BA (NO 3 ) 2 Solution;

[0019] b, add 833 μl of 0.2 mol / L of Eu (NO) to the above solution 3 ) 3 The solution and 2 g of 50 wt% polyacrylic have aqueous solution, stir evenly to give a mixed solution;

[0020] C, place the mixed solution in the reaction kettle, and the hydrothermal reaction was 12h under temperature 140 ° C;

[0021] D. After the hydrothermal reaction, filtration, precipitation was washed, and then the barium oxagle is obtained. Characterization of the product, figure 1 with figure 2 Indicated. by figure 1 It can be seen that the sample size is uniform, good dispersibility, the shape is mulberry, and the diameter is about 5 μm.

Abstract

The invention provides a kind of preparation method of mulberry-shaped barium polyacrylate powder doped with europium, the preparation method comprises the following steps: a, weigh Ba(NO 3 ) 2 Dissolved in water to give Ba(NO 3 ) 2 solution; b, in Ba(NO 3 ) 2 Eu(NO 3 ) 3 Solution and 50wt% polyacrylic acid aqueous solution, stir evenly to obtain a mixed solution; c, put the mixed solution in a reaction kettle, and conduct a hydrothermal reaction at a temperature of 120~140°C for 4~16h; d, filter after the hydrothermal reaction is completed , the resulting precipitate was washed and dried to obtain a mulberry-like europium-doped barium polyacrylate powder. The preparation method of the present invention uses hydrothermal reaction, the preparation method is simple, does not need high-temperature roasting, and is suitable for large-scale industrial production. By controlling the hydrothermal reaction temperature and other conditions, the mulberry-shaped barium polyacrylate powder is obtained. The product size is uniform and stable, the shape is controllable, and it has a large specific surface area and good photoluminescence performance.

Description

Technical field [0001] The present invention relates to the technical field of preparation of luminescent materials, and in particular, to a mulberry-shaped preparation method for producing barium-shaped polyacrylate powder. Background technique [0002] Since the new century, people have more concerned and attach importance to functional materials, and the preparation of new materials has become one of the focus of people's research. In the development of rare earth function materials, especially in rare earth luminescent materials. The rare earth metal has a spectrum properties that have general elements that cannot be combined with a particular element due to its special electronic layer structure. [0003] Polyacrylic acid is a colorless or pale yellow liquid that is capable of forming a stable compound with a metal ion, commonly used as a scale inhibitor and a water absorbing agent. At present, the patent document (such as the document number CN110635C, CN101172718A, etc.) h...
