AGGREGATE OF SEMICONDUCTOR NANOPARTICLE PHOSPHORS, METHOD FOR PRODUCTION OF THE SAME, AND SINGLE-MOLECULE OBSERVATION METHOD USING THE SAME

摘要

Disclosed is an aggregate of semiconductor nanoparticle phosphors, which shows no variation in emission wavelength or luminous intensity among the particles and enables a stable evaluation in the single-molecule observation by using the aggregate as a labeling reagent. Also disclosed is a method for producing the aggregate. Further disclosed is a single-molecule observation method using the aggregate. Specifically disclosed is a method for producing an aggregate of semiconductor nanoparticle phosphors by a liquid phase process, which is characterized by comprising the step of reacting a semiconductor precursor at a temperature equal to or higher than its boiling point and equal to or lower than the boiling point of a solvent.
