Abstract:
1. A method for producing semiconductor nanoparticles comprising: stabilizing a plurality of semiconductor nanoparticles in a solution; irradiating the semiconductor nanoparticles with light to photo-dissolve semiconductor nanoparticles with undesirable diameters therefrom thereby extracting semiconductor nanoparticles of a predetermined average size and a predetermined deviation; chemically modifying surfaces of the extracted semiconductor nanoparticles obtained from the irradiating step with a thiol compound thereby forming a complex; and reacting a compound having a hydroxyl group with the modified surfaces of the semiconductor nanoparticles thereby binding a group —OY to the modified surfaces of the semiconductor nanoparticles for stabilization, Y being selected from a hydrogen atom, a metal atom, a semimetal atom, an organic group, or an organic group that is intermediated by a metal atom or a semimetal atom.
