摘要：
The present invention provides an alloy powder that is a material for producing inorganic functional materials such as phosphors, a phosphor with high brightness, and a method for producing the phosphor. An alloy powder for an inorganic functional material precursor contains at least one metal element and at least one activating element M1 and has a weight-average median diameter D50 of 5 μm to 40 μm. A method for producing a phosphor includes a step of heating an alloy, containing two or more metal elements for forming the phosphor, in a nitrogen-containing atmosphere.
