Novel optical properties of metallic nanocavities0622225Steve BlairUniversity of UtahIntellectual Merit: Plasmonic nanophotonics has been an extremely active research area in recent years, but there remain directions for exploration rich with opportunities for new discoveries and implications for a new generation of engineered photonic devices. The purpose of this research is to explore the emission and energy transfer properties of molecules and quantum dots located within and nearby metal nanocavities; these studies are designed with device applications in mind. A complete picture of the excitation and radiative enhancement mechanisms in metallic nanocavities has yet to be painted; this research will systematically study these enhancement mechanisms and their optimization. One important outcome of these studies lies in the comparison of nanocavity enhancements to published enhancements associated with nanoparticles, which have received much greater attention. In addition, studies of energy transfer mechanisms between donor and acceptor species located within and in proximity to metallic nanocavities will be performed. Overall, these studies have important implications to nanosensors and efficient light-emitting and energy-harvesting devices. Broader Impact: The new generation of nanophotonic devices will have broader impacts with strong societal implications. For example, highly sensitive nanoscale moleculear transducers can form the basis for a new type of microarray which can be used to screen across many thousands of low copy number target species from small initial sample volumes, thus mitigating the need for amplification steps. These types of inexpensive, compact, and highly sensitive microarrays will usher in the new era of personalized medicine, where genetic profiles will be used in the diagnosis and treatment of disease. Students involved in this research will experience an inherently cross-disciplinary environment at the forefront of nanocavity research, which incorporates elements from Electrical Engineering, Bioengineering, Physics, and Chemistry and they will have collaborative opportunities with counterparts from other, international, research groups.

金属纳米腔的新型光学特性0622225Steve utahintlectual功绩的Blairuniversity近年来一直是一个极为活跃的研究领域，但仍存在着探索的方向，但探索的方向充满了新的发现和对新一代工程的光子式启示的新发现的机会。这项研究的目的是探索位于金属纳米腔内和附近的分子和量子点的发射和能量转移特性；这些研究是考虑到设备应用程序的。 金属纳米腔中的激发和辐射增强机制的完整图片尚未绘制。这项研究将系统地研究这些增强机制及其优化。这些研究的一个重要结果在于将纳米腔增强功能与与纳米颗粒相关的已发表增强功能进行比较，而纳米颗粒已受到更大的关注。此外，将对位于金属纳米腔内的供体和受体物种之间的能量转移机制进行研究。 总体而言，这些研究对纳米传感器以及有效的发光和能量收获的设备具有重要意义。更广泛的影响：新一代的纳米光设备将产生更广泛的影响，具有强烈的社会影响。例如，高度敏感的纳米级分子换能器可以为新型微阵列构成基础，该微阵列可用于从小的初始样品体积中筛选数千个低拷贝数目标物种，从而减轻对放大步骤的需求。 这些类型的廉价，紧凑和高度敏感的微阵列将迎来个性化医学的新时代，在这些新时代，遗传特征将用于诊断和治疗疾病。 参与这项研究的学生将在纳米腔研究的最前沿体验固有的跨学科环境，该环境纳入了电气工程，生物工程，物理和化学的元素，他们将与其他，国际，研究小组的同类产品合作。
