Abstract

A novel allempt lo improve the parameters of a NO_x sensor, based on conductivity modulation, is presented. By using tetra-tertbutyl copper phthalocyanine (tlb CuPc) Langmuir-Blodgett (LB) films characterized by high conductivity (10⁻⁶Sm cm⁻¹) and thermostability (up to 160°C) the detection of low NO_x levels (0.l-10³ppm) in air is demonstrated. The response time and the sensitivity are -∼ 1 min and 6nA per decade of NO_x concentration respectively. The selectivity of such a sensor could be explained by the difference of the conductivity activation energies for NO_x (0.63 eV) and oxygen (0.79 eV).
