ZIRCONIUM OXIDE NANOPARTICLE
An object of the present invention is to provide zirconium oxide nanoparticles that have excellent dispersibility in a polar solvent and are capable of increasing a core concentration in a dispersion liquid. Zirconium oxide nanoparticles according to the present invention are coated with at least one compound selected from the group consisting of R 1 -COOH, (R 1 O) 3-n -P(O)-(OH) n , (R 1 ) 3-n -P(O)-(OH) n , (R 1 O)-S(O)(O)-(OH), R 1 -S(O)(O)-(OH), and (R 1 ) 4-m -Si(R 4 ) m , wherein R 1 represents a group comprising a carbon atom and at least one element selected from the group consisting of an oxygen atom, a nitrogen atom, and a sulfur atom, and having the total number of carbon atoms, oxygen atoms, nitrogen atoms, and sulfur atoms of 8 or less.; R 4 represents a halogen atom or -OR 2 , and R 2 represents a hydrogen atom or an alkyl group; and n represents 1 or 2, and m represents an integer of 1 to 3.
