项目摘要

In this project funded by the Macromolecular, Supramolecular and Nanochemistry program of the Chemistry Division, Professor Delia Milliron of the University of Texas at Austin is developing doped metal oxide nanocrystals that can exchange energy with nearby molecules. These new nanoscale building blocks can be widely applied by chemists, materials scientists, and engineers to create functional materials and devices. Professor Milliron is mentoring graduate student, postdoctoral, and undergraduate researchers who are receiving a unique interdisciplinary educational experience, gaining expertise in topics including nanocrystal synthesis, spectroscopy, and simulation of light-matter interactions. Furthermore, Professor Milliron is developing a new educational module for use in pre-college outreach programs that introduce students to plasmonic phenomena and nanochemistry in general.Nanocrystals under development in this project have resonant frequencies in the infrared spectral regime, different from the visible light resonance of classical metal nanoparticles such as gold or silver. Synthetic methods to tune dopant chemistry and dopant distribution are being developed to maximize the potential for near field coupling. Characterization of plasmon-vibrational coupling by Fourier Transform Infrared Spectroscopy complements the synthetic developments underway and lays the foundation for directing energy flow to tune catalytic pathways and to develop advanced sensors and spectroscopic probes.

在该项目由化学部的大分子，超分子和纳米化学计划资助的项目中，德克萨斯大学奥斯汀分校的Delia Milliron教授正在开发可以与附近分子交换能量的掺杂的金属氧化物纳米晶体。这些新的纳米级构件可以由化学家，材料科学家和工程师广泛应用，以创建功能材料和设备。 Milliron教授正在指导研究生，博士后和本科研究人员，他们正在获得独特的跨学科教育经验，并获得了包括纳米晶体合成，光谱和光疗法互动在内的主题方面的专业知识。此外，Milliron教授正在开发一个新的教育模块，用于在大学前外展计划中使用，该模块将学生介绍有关等离子现象和纳米化学。该项目中正在开发的纳米晶体在红外光谱方案中具有共鸣的频率，与可见的金属纳米纳米纳米或金色的可见光共振。正在开发调整掺杂剂化学和掺杂剂分布的合成方法，以最大程度地提高近场耦合的潜力。通过傅立叶变换红外光谱对等离子体振动耦合的表征补充了正在进行的合成发展，并为将能量流带来调整催化途径的基础奠定了基础，并开发了高级传感器和光谱探针。
