Colloidal Engineering of Photonic Materials

提案编号：CTS-0221809首席研究员：Pine，大卫J机构：加州大学圣巴巴拉分校标题：光子材料的胶体工程摘要PI的建议，以研究在乳胶液滴内形成胶体阵列模板“超球”（他们定义为固体球体包含胶体球阵列或由胶体球模板孔）。一些目标包括实现更好地控制超球的大小，通过优化先前开发的中断过程，并通过采用微流体装置;理解孔/胶体订购的超球和乳化的胶体颗粒;和理解的光学性质的超球（光扩散）。此外，PI将尝试在乳液液滴内制备定向胶体，旨在将这些胶体组装成有利于光子材料的非紧密堆积结构。

Proposal Number: CTS-0221809Principal Investigator: Pine, David JInstitution: University of California - Santa BarbaraTitle: Colloidal Engineering of Photonic MaterialsABSTRACTThe PI's propose to study the formation of colloidal arrays within emulsion droplets to template 'supraballs' (which they define as solid spheres containing arrays of colloidal spheres or holes templated by colloidal spheres). Some of the goals include achievement of better control over suprasphere sizes by optimizing a previously developed break-off process and by employing a microfluidic device; understanding of hole/colloid ordering in supraballs and emulsification of colloidal particles; and understanding of optical properties of supraballs (light diffusion). In addition, the PI will attempt to prepare directional colloids within emulsion droplets, intending to assemble these in non close-packed structures which are advantageous for photonic materials.
