ASSEMBLY OF SEMICONDUCTOR NANOPARTICLE PHOSPHORS, PREPARATION METHOD OF THE SAME AND SINGLE-MOLECULE OBSERVATION METHOD USING THE SAME

摘要

Disclosed are an assembly of semiconductor nanoparticle phosphors, which can provide stable evaluation without variation in emission wavelength or in intensity of emission among the particles when used as a labeling agent through which a single-molecule observation is carried out, a preparation method of the assembly, and a single-molecule observation method employing the assembly. Also disclosed is a method for preparing an assembly of semiconductor nanoparticle phosphors according to a liquid phase method, the method comprising the step of reacting a semiconductor precursor at a temperature which is not lower than the melting point of the semiconductor precursor and is not higher than the boiling point of a solvent.
