摘要：

Yttrium oxide films were prepared on indium-tin-oxide (ITO) by electrochemical method followed by heat treatment. During electrochemical reduction, a thin film of yttrium hydroxide was initially formed and vertically oriented growth bands were developed. Structural and morphological changes occurring during the deposition and dehydration of yttrium hydroxides were investigated by use of XRD, SEM and TG/DTA. The extent of dehydration increased with temperature. Y(OH)(3) phase transformed to alpha-Y(OH)(3) at about 400 degrees C, and then Y2O3 above 450 degrees C.
