Abstract

In this work, sulfur-doped mesoporous TiO₂ films were formed by a chemical solution deposition technique to investigate their structure and electrical conductivity. Phase formation and crystallization of TiO₂ was retarded and the optical band gap was reduced due to the presence of the sulfur dopants. As a result, enhancements in the microstructural stability and electrical conductivity of mesoporous TiO₂ could be obtained by sulfur doping.
