Figure 2From: Preparation and near-infrared photothermal conversion property of cesium tungsten oxide nanoparticlesVariation of mean hydrodynamic diameter of Cs 0.33 WO 3 powder with grinding time. Inset a indicates the hydrodynamic diameter distributions of Cs0.33WO3 powder after grinding for 1, 2, and 3 h. Inset b shows the photographs for the aqueous dispersions of Cs0.33WO3 powder before and after grinding for 3 h.Back to article page
