AbstractWe introduce a system of ferroelectric materials, Pb0.3CaxSr0.7-xTiO3[PCST(x), x = 0.00, 0.05, 0.10, and 0.15], which exhibit good pyroelectric properties near room temperature. The enhanced field-induced pyroelectric coefficient of PCST(0.15) reached 81.8 × 10−8C/cm2K and it exhibited the largest voltage response with a dynamic black-body radiation measurement under a DC bias field of 200 V/mm. Systematic dielectric and phase transition analysis of the PCST(x) ceramics demonstrated that the phase transition gradually changed from a second-order to first-order dominated one with increasing Ca ion substitution. The enhanced pyroelectric properties under such a low bias field in the vicinity of room temperature of the PCST(0.15) ceramic are highly desirable for infrared detecting applications. © 2017 Author(s).
