TEM images of In ₂ O ₃ and ITO NPs. TEM images of (a) In₂O₃ (7.3 ± 1.2 nm, 0% Sn), (b) ITO (8.6 ± 1.5 nm, 6% Sn), (c) ITO (7.5 ± 1.7 nm, 7.6% Sn), and (d) ITO (6.3 ± 1.3 nm, 10% Sn) NPs. All the ITO NPs are synthesized by the hot-injection approach using myristic acid. The insets in all the images show the corresponsive HRTEM images of ITO NPs, in which the lattice spacings of 0.293 nm is consistent with the (222) planes of bulk In₂O_3.
