| titleOfInvention | Method for producing red light-emitting material excited by blue light |
| abstract | The present invention provides a method for producing a red light-emitting material excited by blue light without using hydrofluoric acid, wherein the chemical composition of the red light-emitting material is A 2 X 1-y F 6: yMn 4+ , where A Is at least one selected from alkali metal elements; X is at least one selected from Ti, Si, Ge and Zr; y represents the molar percentage coefficient for the Mn 4+ ion to the X 4+ ion, and 0<y≦0.10; The method is a first mixed solution by mixing a substrate material containing X, a mixture of at least one of formic acid, acetic acid and fluoroacetic acid and anhydrous ethanol, or a reaction solvent containing at least one of formic acid, acetic acid and fluoroacetic acid. Obtaining; Adding fluoride of Mn 4+ to the first mixed solution to obtain a second mixed solution; And a step of obtaining a red light-emitting material by adding the fluoride of A to the second mixed solution to obtain a precipitate. This method does not affect environmental pollution. |
