AbstractFerroelectric single crystals Mn-doped 0.29Pb(In1/2Nb1/2)O3-0.31Pb(Mg1/3Nb2/3)O3-0.40PbTiO3(Mn-PIMNT) have been grown by a modified Bridgman technique. The as-grown ternary tetragonal Mn-PIMNT (29/31/40) single crystals exhibit ultra-high Curie temperature TCof 216 °C, 110 °C higher than that of Mn-PMNT(72/28) single crystals(Td∼ 105 °C). In addition, the permittivity Εrof tetragonal Mn-PIMNT(29/31/40) is 350 at 1 kHz, approximately less than that of Mn-PMNT(72/28)(Εr∼ 640) in half. Moreover, as a core parameter of pyroelectric material, the figure of merits for detectivity (Fd) for Mn-PIMNT(29/31/40) is 23.5 × 10−5Pa−1/2, close to that of Mn-PMNT(72/28)(Fd∼ 28.5). Finally, outstanding Mn-PIMNT(29/31/40) based pyroelectric detectors were fabricated, of which the specific detectivity (D*) (room temperature, 10 Hz) is up to 1.74 × 109cmHz1/2/W for current-mode detectors, and 1.15 × 109cmHz1/2/W for voltage-mode detectors, 3 times higher than that of commercial LiTaO3based detectors. All of these results make these ternary tetragonal Mn-PIMNT single crystals a promising candidate for infrared detector applications. © 2016 Elsevier B.V.
