Abstract

The electrical properties of various metal phthalocyanine(MPc) thin film sensors were tested in the presence of $NO_x$ gas. Among the Phthalocyanine(Pc) thin films, lead phthalocyanine(PbPc) thin film showed the best results nd its sensitivity was over 80% at 5ppm of $NO_x$ gas. Optimal operating conditions including response time and cyclic treatment of $NO_x$ were tested and discussed.
