A complexation route mediated synthesis of orthorhombic antimony sulfide nanoparticles is described in this report where uniformly distributed particles within the size range of 2-12 nm are stabilized within the aniline matrix. The organic-inorganic hybrid system was investigated for dielectric capacitance and electric field-induced polarization performances under varying temperature and frequency conditions. The AC-conductivity revealed a correlated barrier hopping conduction mechanism in the hybrid system. A fatigue free polarization was achieved under the electric field of 9 kV mm for the preformed antimony sulfide system with a stable value of 0.18 μC cm. The dielectric capacitance and field dependent polarization measurements were also performed for the synthesized antimony sulfide using the antimony-aniline complex as the precursor.
本报告描述了一种通过络合路线介导合成正交晶系硫化锑纳米颗粒的方法,其中尺寸范围在2-12纳米内均匀分布的颗粒在苯胺基质中得以稳定。研究了该有机-无机杂化体系在不同温度和频率条件下的介电电容和电场诱导极化性能。交流电导率揭示了杂化体系中的相关势垒跳跃传导机制。对于预先形成的硫化锑体系,在9 kV/mm的电场下实现了无疲劳极化,稳定值为0.18 μC/cm²。还使用锑-苯胺络合物作为前驱体对合成的硫化锑进行了介电电容和场依赖极化测量。
