Description
Summary:Ce-doped SnO2 materials with rutile type structure were obtained as porous ceramic, powders and films from different precursor mixtures and by using different preparation routes. The samples were characterised in terms of their structural, morphological and electrical properties. Depending on the specific precursor mixture, different microstructural parameters were obtained. The lattice parameters of the host oxide (SnO2) decreased by CeO2 doping and the mean crystallite size D varied in the range 67-127.8 nm. Different values of lattice strain S were also noticed. Morphological characteristics such as shrinkage, porosity, density and BET surface area were determined. The electrical properties were measured on the porous ceramics and on the powders. All samples showed n-type semiconducting behaviour. 15 refs.
