Nanostructured CexZn1−xO thin films: Influence of Ce doping on the structural, optical and electrical properties

Highlights
- Thin films of Ce doped ZnO were prepared by nebulizer spray pyrolysis technique.
- Films were deposited at different cerium concentrations 2.5%, 5.0%, 7.5% and 10%.
- Ce doped ZnO films are found to have more grains along [0 0 2] direction.
- The band gap energy was found to be decreased with the increase of Ce doping.
- CexZn1−xO films ensure their stability and suitability for gas sensors.
