| 英文摘要 | Both high pyroelectric properties and good temperature stability of ferroelectric materials are desirable when used for applications in infrared thermal detectors. In this work, we report leadfree ternary 0.97(0.99Bi(0.5)Na(0.5)TiO(3)-0.01BiAlO(3))-0.03K(0.5)Na(0.5)NbO(3) (BNT-BA-KNN) ceramics, which not only exhibits a large pyroelectric coefficient (p similar to 3.7 x 10(-8) C cm(-2) K-1) and figures of merit (F-i, F-v, and F-d) but also shows excellent thermal stable properties. At room temperature, F-i, F-v, and F-d are determined as high as 1.32 x 10(-10) m/V, 2.89 x 10(-2) m(2)/C, and 1.15 x 10(-5) Pa-1/2 at 1 kHz and 1.32 x 10(-10) m/V, 2.70 x 10(-2) m(2)/C, and 1.09 x 10(-5) Pa-1/2 at 20 Hz, respectively. During the temperature range of RT to 85 degrees C, the achieved p, F-i, F-v, and F-d do not vary too much. The high depolarization temperature and the undispersed ferroelectric-ergodic relaxor phase transition with a sharp pyroelectric coefficient peak value of similar to 400 x 10(-8) C cm(-2) K-1 are suggested to be responsible for this thermal stability, which ensures reliable actual operation. The results reveal the BNT-BA-KNN ceramics as promising lead-free candidates for infrared thermal detector applications. Published by AIP Publishing. |
