摘要： Infrared absorbing particles include composite tungsten oxide particles, wherein the composite tungsten oxide particles have a hexagonal crystal structure, and wherein the composite tungsten oxide particles are represented by a general formula M x W y O z (where M is one or more elements selected from Cs, Rb, K, Tl, Ba, Ca, Sr, and Fe, W is tungsten, O is oxygen, 0.25 ≤ x/y ≤ 0.39, and 2.70 ≤ z/y ≤ 2.90).
