Abstract
A semiconductor nanoparticle complex in which two or more ligands including an aliphatic ligand and a polar ligand are coordinated to a surface of a semiconductor nanoparticle, wherein: the ligands are composed of an organic group and a coordinating group; in the aliphatic ligand, the organic group is an aliphatic hydrocarbon group; the polar ligand includes a hydrophilic functional group in the organic group; a mass ratio of the aliphatic ligand to the polar ligand (aliphatic ligand/polar ligand) is 0.05 to 1.00; a ratio ({(X)/L}×100) of a mass reduction rate of the semiconductor nanoparticle complex in a range of 350° C. or higher and 550° C. or lower in a thermogravimetric analysis (X) to a mass fraction of all ligands in the semiconductor nanoparticle complex at room temperature (L) is 10 or more and 55 or less.
