项目摘要
Objective: The objective of this program is to explore an innovative concept that leads to microstructured sapphire fibers with porous, anodized aluminum oxide as cladding that further functions as anchor of Au and Ag nanoparticles for chemical sensing and measurements by surface-enhanced Raman scattering at high temperatures. Intellectual Merit: The intellectual merit is to theoretically calculate mode-field distribution in the porous aluminum oxide cladding to determine the optimal microstructure of the oxide for high mode-field overlap and thus strong light-analyte interactions; to use the calculated results as a guide to coat and anodize Al coating on sapphire fiber to obtain porous oxide-cladded microstructured sapphire fiber; and to evaluate the feasibility of microstructured sapphire fibers decorated with Ag and Au nanoparticles for SERS measurements of hot combustion gas at 500º-1500ºC. The program is transformative in that it will help usher in a new category of specialty optical fibers for demanding applications where existing fiber technologies are not suitable.Broader Impacts: The broader impacts are multi-faceted. Technologically speaking, optically coupled microstructured sapphire fibers could be used as a micro-reactor or test bed for the development and understanding of new catalytic phenomena with laser spectroscopy as a powerful in-situ probing technique. From educational perspective, this program will provide a fertile training ground for a graduate student and a diverse group of undergraduate and high school students. The collaboration with Czech researchers adds a significant international dimension. Dissemination of research results will be achieved via conference presentations and peer-reviewed publications.
目的:该计划的目的是探索一种创新的概念,导致微结构蓝宝石光纤与多孔,阳极氧化铝作为包层,进一步作为Au和Ag纳米粒子的锚的化学传感和测量的表面增强拉曼散射在高温下。智力优势:理论上计算了多孔氧化铝包层中的模场分布,确定了高模场重叠和强光-分析物相互作用的最佳氧化物微结构,并以此为指导在蓝宝石光纤上涂覆和阳极氧化铝涂层,获得了多孔氧化物包层微结构蓝宝石光纤;并评估用Ag和Au纳米颗粒修饰的微结构蓝宝石光纤用于500º-1500播放C的热燃烧气体的Sers测量的可行性。该计划具有变革性,因为它将有助于引入一种新的特种光纤类别,用于现有光纤技术不适用的苛刻应用。更广泛的影响:更广泛的影响是多方面的。从技术上讲,光耦合微结构蓝宝石光纤可以用作微反应器或测试床,用于开发和理解新的催化现象,激光光谱学作为一种强大的原位探测技术。从教育的角度来看,该计划将提供一个肥沃的培训基地,为研究生和本科生和高中生的多样化群体。与捷克研究人员的合作增加了一个重要的国际层面。研究成果的传播将通过会议介绍和同行评审的出版物来实现。
