| titleOfInvention | The preparation method and product of fluosilicate red fluorescence powder and combinations thereof and application |
| abstract | The present invention provides a kind of preparation method of fluosilicate red fluorescence powder, and the red fluorescence powder is represented by general formula I：M 2 SiF 6 :Mn 4+ (I), wherein, M is selected from one or both of K and Na, and the preparation method comprises the following steps：(1) by MMnO 4 Stirring is added into hydrofluoric acid to being uniformly mixed with MF, and H is added dropwise 2 O 2 Untill solution colour changes, mixed liquor is obtained；(2) material of powdered silicon oxide-containing is added in the mixed liquor while stirring, first heating makes it fully react, and rear cooling separates out crystallization, and yellow solid is obtained after filtering；(3) yellow solid obtained respectively with a small amount of pure water and organic solvent to step (2) washs, and the red fluorescence powder is obtained after drying process.The preparation method of the composition containing the fluorescent powder is additionally provided, uses red fluorescence powder made from the above method or the composition containing the fluorescent powder, and the fluorescent powder or the purposes containing its composition in LED illumination or back light member or equipment. |
