Compared with other methods, the present solvent thermal method can produce ITO nano-powders with high purity and uniform particle size. The manipulation is very simple and convenient and no calcination process is needed. The reaction temperature can be as low as 190 ℃, which is by far the lowest temperature in ITO nano-powder preparation. The sample also gives a good dispersion property benefited from the unique solvent thermal reaction environment.
