摘要：

The chlorine sensitivity of thin films of monoclinic lead phthalocyanine has been studied. The temporal behaviour of the dark conductivity during chlorine exposure has been interpreted on the basis of the creation of acceptor states both on the surface and in the bulk. Support for this model is provided by observations of bulk diffusion of the chlorine, and an approximate diffusion rate at room temperature has been determined. These observations suggest that bulk diffusion, which has received relatively little attention in previous studies of phthalocyanine gas sensors, may warrant a more detailed investigation.
