Abstract
Results of investigations aimed at creating a material possessing selective sensitivity to gaseous hydrogen sulfide are presented. Polycrystalline fil ms of doped tin dioxide were obtained by pyrolysis of an aerosol of appropr iate organometallic compounds. The effect of copper and nickel oxides on th e electrical properties, actual structure, and composition of polycrystalli ne tin dioxide films was studied. The influence of trace amounts of gaseous H2S on the electrical conductivity of the films was analyzed in detail.
