在液晶分子存在下，通过紫外线照射乙酸钯(II)的醇溶液制备了覆盖有液晶分子的钯纳米颗粒。制备的Pd纳米颗粒的平均直径为2.5 nm。通过掺杂被另一种向列液晶分子覆盖的 Pd 纳米颗粒，制造了扭曲向列 (TN) 液晶器件 (LCD)。在该器件中，覆盖 Pd 纳米颗粒的液晶分子的介电各向异性 (Deltaepsilon) 的符号与作为器件主体的向列液晶分子的介电各向异性 (Deltaepsilon>0) 的符号相反。本研究中制造的 TN-LCD 单元对所施加的交流电压波形表现出频率调制响应。 (C) 2002 年美国物理研究所。
Palladium nanoparticles covered with liquid-crystal molecules were prepared by UV irradiation of an alcohol solution of palladium(II) acetate in the presence of liquid-crystal molecules. The prepared Pd nanoparticles have an average diameter of 2.5 nm. A twisted nematic (TN) liquid-crystal device (LCD) was fabricated by doping with Pd nanoparticles covered with another kind of nematic liquid-crystal molecules. In this device the sign of the dielectric anisotropy (Deltaepsilon) of the liquid-crystal molecules, which cover Pd nanoparticles, is opposite to that of nematic liquid-crystal molecules, which work as the host of the device (Deltaepsilon>0). The TN-LCD cell fabricated in this research exhibits a frequency modulation response to an applied alternative voltage wave form. (C) 2002 American Institute of Physics.
