This CAREER award is co-funded by the Electronic Materials Program in the Division of Materials Research and the Experimental Physical Chemistry Program in the Chemistry Division.Technical: The project is to study three-dimensional (3D) metallodielectric metamaterials, which are fabricated using multiphoton direct laser writing, followed by metallization by nanoparticles binding and/or electrolessly plating of the scaffold surface. Using multiphoton direct laser writing, polymeric 3D lattices having virtually any micrometer-scale geometry can be created in a single photo-patterning step. Single nanoparticles, nanoparticles clusters, or continuous metal can then be deposited conformably onto the lattice, providing control over the metal nano-scale morphology. The objectives of the research are to investigate and learn to control processing, deposition, and growth phenomena relevant to preparing 3D optical metallodielectric materials and to develop predictive capabilities that relate the resulting nanometer- and micrometer-scale structures of these materials to their electromagnetic properties and device performance, thereby enabling new applications, which may include broad-band electromagnetic filtering and cloaking; sub-wavelength focusing; ultra-small and high-efficiency lasing; and low-intensity, all-optical switching.Non-technical: The project addresses basic research issues in a topical area of materials science, chemistry, nanotechnology, and optics with high technological relevance, and is expected to provide a flexible new route to fabricate three-dimensional metamaterials, which exhibit fascinating optical properties, such as ultra-wide plasmonic band gaps, optical magnetism, extrinsically modified absorption/emission, and negative refractive index. The technical project is integrated with education via the PI's classroom teaching; research training; and a peer-to-peer outreach designed to attract middle-school, high-school, and community-college students to science and technical careers. The research is expected to generate exciting content for the outreach program and the PI's teaching. The outreach has the potential to impact a large number of youths across multi-ethnic Central Florida through partnerships with Orange Co. Public Schools, Valencia Community College, and Seminole Community College. The project will also provide a superb context for interdisciplinary training of graduate and undergraduate students.

该CAREER奖由材料研究部的电子材料项目和化学部的实验物理化学项目共同资助。技术：该项目是研究三维（3D）金属介电超材料，该材料使用多光子直接激光写入，然后通过纳米颗粒结合和/或支架表面的无电镀金属化来制造。使用多光子直接激光写入，可以在单个光图案化步骤中创建具有几乎任何微米级几何形状的聚合物3D晶格。然后，单个纳米颗粒、纳米颗粒簇或连续金属可以共形地沉积到晶格上，从而提供对金属纳米级形态的控制。研究的目标是调查和学习控制与制备3D光学金属电介质材料相关的加工、沉积和生长现象，并开发预测能力，将这些材料的纳米和微米级结构与其电磁特性和器件性能联系起来，从而实现新的应用，其中可能包括宽带电磁滤波和隐身;亚波长聚焦;超小型高效激光;低强度全光开关。非技术性：该项目解决了材料科学，化学，纳米技术和光学领域的基础研究问题，具有高度的技术相关性，并有望提供一种灵活的新途径来制造三维超材料，这些材料具有迷人的光学特性，例如超宽等离子体带隙、光学磁性、外延改性吸收/发射和负折射率。该技术项目通过PI的课堂教学与教育相结合;研究培训;以及旨在吸引初中，高中和社区大学学生从事科学和技术职业的点对点推广。这项研究预计将产生令人兴奋的内容外展计划和PI的教学。通过与瓦伦西亚社区学院、橙子公司公立学校和塞米诺尔社区学院的合作，这项推广活动有可能影响到佛罗里达中部多民族的大量青年。该项目还将为研究生和本科生的跨学科培训提供极好的环境。
