SEMICONDUCTOR NANOPARTICLES, DISPERSION LIQUID, FILM, AND METHOD FOR PRODUCING SEMICONDUCTOR NANOPARTICLES

摘要

The present invention addresses the problem of providing semiconductor nanoparticles having high luminous efficiency and excellent durability and a method for producing the same, and dispersion liquid and a film which use the semiconductor nanoparticles. In these semiconductor nanoparticles, oxygen, zinc, and sulfur are detected by X-ray photoelectron spectroscopy, and peaks (I_CH3) present in 2800 cm^-1 to 3000 cm^-1 derived from hydrocarbon groups and peaks (I_COO) present in 1400 cm^-1 to 1600 cm^-1 derived from COO- are detected by Fourier transform infrared spectrometry.
