Colloidal Engineering of Photonic Materials

项目编号：csts -0221809首席研究员：Pine， David j机构：加州大学圣巴巴拉分校标题：光子材料胶体工程摘要该项目建议研究乳液液滴内胶体阵列的形成，以模板“超级球”（他们将其定义为包含胶体球阵列或由胶体球模板的孔的固体球体）。一些目标包括通过优化先前开发的切断过程和采用微流体装置来实现对超球面尺寸的更好控制；超球孔/胶体有序及胶体乳化的研究以及对超球光学性质（光扩散）的理解。此外，PI将尝试在乳液液滴内制备定向胶体，意图将这些胶体组装成有利于光子材料的非紧密排列结构。

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.
