Title: Alloy powder for material of inorganic functional material precursor and phosphor

Abstract: 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 M.sup.1 and has a weight-average median diameter D.sub.50 of 5 .mu.m to 40 .mu.m. 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.
