Reactive temperature and growth time effects on the morphology of PMN–PT nanorods by hydrothermal synthesis

• 0.65(Mg1/3Nb2/3)O3–0.35PbTiO3 (PMN–PT) nanorods were prepared by the hydrothermal method.
• The hydrothermal temperature and reaction time have importance influence on the morphology of PMN–PT Nanorods.
• The coercive field, remnant polarization and spontaneous polarization of PMN–PT Nrs are: 2.78 kV/mm, 17.08 μc/cm2 and 31.25 μc/cm2.

Single crystalline nanorod (Nr) is considered to be a promising candidate in many nano-electric devices due to its excellent electric properties. Here we report a method to fabricate 0.65(Mg1/3Nb2/3)O3–0.35PbTiO3 (PMN–PT) single crystalline Nr by controlling the hydrothermal synthesis temperature and reactive time. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) have been employed to investigate the morphology and crystal characteristics of the PMN–PT Nrs. It was confirmed that single crystalline PMN–PT Nrs have been fabricated under optimal synthesis condition. Finally, the ferroelectric properties of PMN–PT Nrs were measured, and the coercive field, remnant polarization and spontaneous polarization of the nanorods are 2.78 kV/mm, 17.08 μC/cm2 and 31.25 μC/cm2 respectively.
