Abstract
The pyroelectric characteristics for 0.8 Pb(Zn1/3Nb2/3)O3 - 0.1 PbTiO3 - 0.1 BaTiO3 ceramics were investigated to determine the usefulness of this material as an uncooled infrared detector. Two successive phase transitions, changing the crystal symmetry from rhombohedral to tetragonal, and then to cubic on a heating process, were observed in the material. The results of measurements were compared with those of PLZT (8/40/60) and the Ca-Modified PbTiO3, which are currently the favored materials for uncooled arrays. The results indicate that 0.8 PZN - 0.1 PT - 0.1 BT is a promising material for both transverse mode and pyroelectric CCD arrays.
