Abstract :
Lead phthalocyanine (PbPc) single crystal whiskers were grown in vacuum via physical vapor deposition technique. The individual whiskers were used as gas-sensing elements of the conductometric gas sensing devices. These chemiresistors were found to respond sensitively and selectively to NO2. High crystallinity and high surface to bulk ratio determine the advantageous stability and time response characteristics of such sensing elements in comparison with polycrystalline films.
