WIPO Patent Application WO/2020/250663
Kind Code:
A1
Abstract:
This semiconductor nanoparticle complex, in which ligands are coordinated on the surface of a semiconductor nanoparticle, is characterized in that the semiconductor nanoparticle is a core-shell type semiconductor nanoparticle having a core containing In and P, and one or more layers of shell, the semiconductor nanoparticle further contains a halogen, the molar ratio of the halogen to In in the semiconductor nanoparticle is 0.80-15.00 on an atomic basis, the ligands include one or more mercapto fatty acid esters represented by general formula (1): HS-R1-COO-R2 (1), the mercapto fatty acid esters have an SP value of 9.20 or more, the mercapto fatty acid esters have a molecular weight of 700 or less, and the average SP value of all the ligands is 9.10-11.00. According to the present invention, provided is a semiconductor nanoparticle complex that can be dispersed at a high mass fraction in a dispersion medium having polarity with the fluorescence quantum yield (QY) of the semiconductor nanoparticle maintained high.
