The modified lead titanate (PT) based thick films were fabricated using thick film transfer (TFT) technique. The pyroelectric and dielectric behavior ascertained plausible usage as infrared detectors for these films. The conduction processes in these films are represented by the development of an equivalent circuit model that portrays a near perfect dielectric material containing traps. Various “materials’ figures-of-merit” of modified PT films are determined for their potential use as infrared detector. Based on existing information these material properties are found to be reasonable.
