Abstract
Provided are a method for manufacturing a phosphor ceramic that emits light when excited by excitation light, and a method for manufacturing a light-emitting device. The method for manufacturing a phosphor ceramic includes preparing a precursor that is either a molded body containing aluminum nitride or a sintered body containing aluminum nitride, and producing an aluminum nitride phosphor ceramic having a content of europium in a range from greater than 0.03 mass % to 1.5 mass % by bringing the precursor into contact with a gas containing europium.
