摘要：

The influence of zinc salt on the nature of ZnO powders prepared by spray pyrolysis has been studied. Powders with a wide variety in the state of aggregation of the particles can be obtained by selecting the type and concentration of the salt. Doping with cobalt results in homogeneous Zn/Co mixed oxides to a 1-mu-m level. At atomic ratios of Zn/Co higher than 50%, CoO is stabilized along with the ZnO particles, but at lower Zn/Co atomic ratios the low temperature stable phase, Co3O4, is formed.
