Abstract: The present disclosure provides a method for fabricating a phosphor. A first solution is formed by dissolving potassium hexafluorogermanate (K2GeF6) and either K2MnF6 or KMnO4 in a hydrofluoric acid solution. An anhydrous ethanol is added to the first solution to make a total concentration of fluoride ions of potassium hexafluorogermanate (K2GeF6), hydrofluoric acid, and either K2MnF6 or KMnO4 equal to or less than 48M to form a precipitate. Afterward, the precipitate is collected.
