Doped (F, Sb, Mo) tin(IV) oxide (SnO[sub 2]) films are used as transparent-conductive electrodes in electrochromic devices (ECD), and low-emitting (i.e, heat reflecting) coatings for advanced glazing in solar applications. Thin SnO[sub 2] and Sb-doped SnO[sub 2] films have been prepared from aqueous colloidal solutions containing SnCl[sub 4][center dot]5H[sub 2]O and SbCl[sub 3] precursors by the dip-coating technique. The films are characterized as small grains (40 to 70 [angstrom]) and exhibit the ability to uptake reversibly Li[sup +] and H[sup +] ions from solutions of LiClO[sub 4] (0.1M) in acetonitrile (AN) or water, LiOH (0.1M) and HCIO[sub 4] (0.001 to 0.01 M). It was found that Sb-doped (7 a/o Sb) SnO[sub 2] films thicker than 100 nm exhibit about three times greater (de) inserted charges as compared to the undoped films. With regard to the amount of (de) inserted charge (up to 8 mC/cm[sup 2]), Sb-doped SnO[sub 2] films are suitable for mixed electronically conductive, ion-storage electrodes in electrochromic devices.
