Abstract

In this study, the co-doping effect of ZnO and Sb₂O₅ on the solubility limit in SnO₂ was investigated. When ZnO was added to SnO₂, its solubility limit was around 3 at%, while that of Sb ₂O₅ could not be evaluated due to the severe evaporation of Sb₂O₅ during sintering. For the co-doping of ZnO and Sb₂O₅, the ZnSb₂O₆ phase was used for the source of Zn and Sb dopants to prevent the evaporation of Sb ₂O₅. When ZnO and Sb₂O₅ were co-doped by ZnSb₂O₆, the solubility limit expanded to 60 at%. XPS analysis of the Sb revealed that Sb⁵⁺ is stable when Zn is co-doped. The extended solubility limit is explained by electrostatic and strain energy minimization in the lattice.
