Preparation of corundum structure Sn-doped In2O3 nanoparticles via controlled co-precipitating and postannealing route

Corundum structure Sn-doped In2O3 nanoparticles were first synthesized by a controlled co-precipitating and postannealing method. X-ray powder diffraction (XRD), electron diffraction (ED), transmission electron microscopy (TEM), and X-ray photoelectron spectrometer (XPS) were used to characterize the products, indicating that the products were well-crystallized Sn-doped In2O3 nanoparticles with corundum structure. The particles were spherical in shape with sizes in the range of 10–20 nm.
