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