| Abstract: | The tin dioxide ultrafine particle films with the average particle size of 40 nmhave been deposited by DC gas discharge activating reaction evaporation technique. Themophology,structure and composition of the films preparated at various oxygen partialpressure was discussed. The gas sensing properties of these samples to various in-flammable gases were also studied. The curves of the sensitivity as a function of oxygengas pressure and the sensors operating temperature were obtainde,respectively. |
