PSSM Workshop on Liquid Crystals and Colloidal Dispersions
Assembly and Alignment of Plasmonic Nanoparticles by Lyotropic Liquid Crystals.
Qingkun Liu, Zhejiang University
Abstract: In this work, we study self-assembly and self-alignment of the gold nanorods dispersed in nematic and hexagonal lyotropic liquid crystals as well as explore novel the plasmonic effects arising from the unidirectional ordering of gold nanorods in these soft materials. To obtain uniform alignment of the lyotropic liquid crystal host medium, we use different alignment technologies such as strong magnetic field and shear alignment, which allows us to achieve controlled assembly in the composite nanoparticle-doped liquid crystals. Several characterization techniques, such as polarized optical microscopy, fluorescence confocal polarizing microscopy, spectroscopy, freeze-fracture electron microscopy, and others are used to explore the assembly of nanorods by liquid crystals and the polarization and thermal dependence of the plasmonic effects. We acknowledge support of the International Institute for Complex Adaptive Matter (ICAM-I2CAM).
