摘要：

A one-pot synthesis of colloidal, monodisperse, and highly crystalline tin-doped indium oxide (ITO) nanoparticles of various sizes with variable tin oxide content and their optical properties was reported depending on the particle size and Sn content. The selected area electron diffraction (SAED) pattern of the nanoparticles is found to be consistent with the cubic bixbyite structure of In2O3. The X Ray Diffraction (XRD) pattern show a highly crystalline nature for the various sizes of 5 atom % of Sn doped ITO nanoparticles. The Sn:In raito in as-synthesized ITI nanoparticles analyzed by ICP-AES show that the final composition of the nanoparticles coincide with the initial molar ratios of the two starting metal mrecursors used in the synthesis. The results also show that as the Sn content increases, the photoluminescence (PL) emission maxima become blue-shifted.
