Abstract: The method for producing light-emitting particles each having a surface layer containing Si on a surface of a semiconductor nanocrystal particle composed of a metal halide includes the steps of: forming the semiconductor nanocrystal particle and a poly-siloxane bond from a solution containing a raw material for the semiconductor nanocrystal particle, a silane compound A having a binding group and a hydrolyzable silyl group, and a solvent, to obtain a precursor particle; mixing the precursor particle, a polymer B containing a structural unit having a basic group and a solvophilic structural unit, and a solvent to obtain a mixture; and adding a silane compound C having a hydrolyzable silyl group to the mixture to obtain a light-emitting particle having a layer containing the polymer B and a polymer of the silane compound C on a surface of the precursor particle.
