This invention teaches a method for fabricating an array (1) of pyroelectric detectors (10), and further teaches an array (1) of pyroelectric detectors (10) that include a bismuth layered compound. The array has a substrate (12) and a plurality of pyroelectric detector sites disposed over a surface of the substrate. Each of the pyroelectric detector sites is constructed to have a first electrode (16); a second electrode (20); and a thin layer (18) containing a bismuth layered compound that is interposed between and electrically coupled to the first and second electrodes. In one embodiment the thin layer is comprised of Y1 material (SrBi.sub.2 Ta.sub.2 O.sub.9), while in another embodiment the layer is comprised instead of YZ material (SrBi.sub.2 Nb.sub.2-x Ta.sub.x O.sub.9).
