Abstract
This paper describes the results of the action of gaseous NO2 on the s emiconducting properties of lutetium phthalo-naphthalocyanine thin fil ms. They are compared to those already presented on the interaction be tween NO2 and lutetium diphthalocyanine or copper phthalocyanine thin films. The difference in behaviour among the three compounds in the pr esence of NO2 is due to (i) the different intrinsic charge carrier con centrations, (ii) the more or less good ability to undergo redox react ions with dopants, and (iii) the polycrystalline or quasi-amorphous st ructures of the thin films which influence the diffusion rate of the g as within the layers.
