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.

在这个由化学系的大分子、超分子和纳米化学项目资助的项目中，德克萨斯大学奥斯汀分校的迪利亚·米利龙教授正在开发掺杂的金属氧化物纳米晶体，它可以与附近的分子交换能量。这些新的纳米结构单元可以被化学家、材料科学家和工程师广泛应用于制造功能材料和设备。教授Milliron是指导研究生，博士后和本科研究人员谁正在接受一个独特的跨学科的教育经验，获得专业知识的主题，包括光合成，光谱学和光物质相互作用的模拟。此外，Milliron教授正在开发一个新的教育模块，用于大学预科课程，向学生介绍等离子体现象和纳米化学。该项目正在开发的纳米晶体具有红外光谱范围的共振频率，不同于经典金属纳米颗粒（如金或银）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，以最大化近场耦合的潜力。通过傅里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开发，并为引导能量流以调节催化途径和开发先进的传感器和光谱探针奠定了基础。
