SEMICONDUCTOR NANOPARTICLE, ITS PREPARATION METHOD, AND SEMICONDUCTOR NANOPARTICLE FLUORESCENCE REAGENT

摘要

PROBLEM TO BE SOLVED: To obtain a semiconductor nanoparticle which has a fluorescent characteristic of emitting only bandgap fluorescence notably by stabilizing the surface of the semiconductor nanoparticle by modifying the surface with a hydroxy group or the like.;SOLUTION: There are provided the semiconductor nanoparticle having the fluorescent characteristic which bears on the surface thereof a modifying group represented by formula (1), its preparation method, and the semiconductor nanoparticle fluorescence reagent. In the formula, Y is chosen from a hydrogen atom, a metal atom, a semi-metal atom, an organic group, and an organic group which is linked via a metal atom or a semi-metal atom.;COPYRIGHT: (C)2004,JPO
