Abstract

To enhance the service temperature of relaxor- PbTiO3 pyroelectric single crystals, high quality ternary perovskite single crystal was grown by a modified Bridgman technique. Analyzed by x-ray fluorescence, the as-grown crystal is 0.41Pb (In12 Nb12) O3 -0.17Pb (Mg 13 Nb23) O3 -0.42PbTiO3 [PIMNT(41/17/42)], which appears to be a tetragonal ferroelectric phase with relatively high Curie temperature of 253 °C. It exhibits the relative permittivity of 487 and low dielectric loss of 0.3% at 50 Hz and room temperature. The pyroelectric properties with a pyroelectric coefficient of 5.7× 10-4 Cm2 K and a detectivity of 6.34× 10-5 Pa-12 would satisfy the needs of operation as a high Curie temperature material. The results show that PIMNT crystal with better temperature stability, compared with the pure PMNT single crystals, is a good candidate as an infrared detector material.
