Semiconductor nanoparticle, dispersion liquid, film, and method of producing semiconductor nanoparticle

摘要

An object of the present invention is to provide a semiconductor nanoparticle having high emission efficiency and excellent durability; a method of producing the same; and a dispersion liquid and a film obtained by using a semiconductor nanoparticle. The semiconductor nanoparticle of the present invention is a semiconductor nanoparticle in which oxygen, zinc, and sulfur are detected by X-ray photoelectron spectroscopy analysis and a peak (I_CH3) which is derived from a hydrocarbon group and present in a range of 2800 cm⁻¹ to 3000 cm⁻¹ and a peak (I_COO) which is derived from COO⁻ and present in a range of 1400 cm⁻¹ to 1600 cm⁻¹ are detected by Fourier transform infrared spectroscopy analysis.
