An organically modified metal oxide nanoparticle includes a core, a first modification group, and a second modification group. The core includes a plurality of metal atoms and a plurality of oxygen atoms bonded to the plurality of metal atoms. The first modification group is a saturated carboxylic acid/carboxylate ligand coordinated to the core. The second modification group is coordinated to the core, and is an inorganic anion having a smaller size than the first modification group and/or a saturated carboxylic acid/carboxylate ligand having a smaller molecular weight than the first modification group.
