Abstract
Provided is an infrared-shielding nanoparticle dispersion that has a property whereby visible light is adequately transmitted, and light in the near-infrared region is adequately shielded. The infrared-shielding nanoparticles include a plural aggregate of electroconductive particles composed of a tungsten oxide expressed by the general formula WyOz (where W is tungsten, O is oxygen, and 2.2≦z/y≦2.999), and/or a composite tungsten oxide expressed by the general formula MxWyOz (where M is one or more elements selected from H, alkali metals, alkaline-earth metals, rare earth elements, Mg, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Al, Ga, In, Tl, Si, Ge, Sn, Pb, Sb, B, F, P, S, Se, Br, Te, Ti, Nb, V, Mo, Ta, Re, Be, Hf, Os, Bi, and I; W is tungsten; O is oxygen; 0.001≦x/y≦1.1; and 2.2≦z/y≦3.0).
