摘要：

Gas sensors based on nanocrystalline SnO2 powders were prepared by a laser evaporation and gas-phase condensation route. These sensors were found to offer enhanced sensitivity compared with materials prepared by conventional methods. Due to the well-defined grain-size distribution and close control of average particle size, a high degree of reproducibility for sensing films prepared from different batches of material was obtained.
