Photopyroelectric spectroscopy (PPES), in the 400 Ο½ Ο½ 900 nm wavelength range, was used to study thermal properties of differently doped polyaniline (PAN) films. The photopyroelectric intensity signal V n () and its phase F n () were independently measured, as well as the intensity V n (f) and the p
In this work we present the quantitative and qualitative detection of organic vapours by a photopyroelectric (PPE) sensor. The PPE sensor consists of a pyroelectric detector covered with a sensitive polymer film. The vapour is sorbed within the film and excited by infrared radiation. The heat obtain
