| titleOfInvention | Preparation method of mulberry-shaped europium-doped barium polyacrylate powder |
| abstract | The invention provides a preparation method of mulberry-shaped europium-doped barium polyacrylate powder, which comprises the following steps: a. weighing Ba (NO) 3 ) 2 Dissolving in water to obtain Ba (NO) 3 ) 2 A solution; b. in Ba (NO) 3 ) 2 Adding Eu (NO) into the solution 3 ) 3 Uniformly stirring the solution and 50wt% of polyacrylic acid aqueous solution to obtain a mixed solution; c. placing the mixed solution in a reaction kettle, and carrying out hydrothermal reaction for 4-16 h at the temperature of 120-140 ℃; d. and filtering after the hydrothermal reaction is finished, and washing and drying the obtained precipitate to obtain mulberry-shaped europium-doped barium polyacrylate powder. The preparation method uses hydrothermal reaction, is simple, does not need high-temperature roasting, and is suitable for large-scale industrial production. The mulberry-shaped barium polyacrylate powder is obtained by controlling conditions such as hydrothermal reaction temperature, and the product has uniform and stable size, controllable appearance, larger specific surface area and good photoluminescence performance. |
