ALLOY POWDER FOR RAW MATERIAL OF INORGANIC FUNCTIONAL MATERIAL AND PHOSPHOR

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 M 1 and has a weight-average median diameter D 50 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.
