Abstract
Thin-film structures of inorganic and organic electron-, defectelectron-, and ion-conducting materials were optimized to detect selectively NO2 in the gas phase for environmental control applications. We present results on electronic conductance sensors based upon SnO2 and PbPc, and on potentiometric sensors based upon the solid-state electrochemical cell Ag/AgI/PbPc/C.Keywords
