Abstract	To support practical infrared detector applications, pyroelectric ceramics should exhibit excellent pyroelectric performances, high depolarization temperatures, and good thermal stabilities. In this study, the pyroelectric properties, depolarization behaviors, and thermal stabilities of tetragonal 0.8Bi(0.5)Na(0.5)TiO(3)-0.2BaTiO(3) (0.8BNT-0.2BT) ceramics are studied systematically. The samples exhibit high depolarization temperatures (similar to 209 degrees C) and excellent thermal stabilities. More importantly, they display high pyroelectric coefficients (p = 2.42 x 10(-8) C cm(-2) K-1), as well as high voltage responsivity (F-v = 2.68 x 10(-2) m C-1) and specific detectivity (F-d = 1.53 x 10(-5) Pa-1/2) figures of merit at room temperature and 1 kHz. The overall properties of tetragonal 0.8BNT-0.2BT ceramics indicate their potential for application in infrared detectors. Published under license by AIP Publishing.
