MRI: Acquisition of a Cathodoluminescence Spectrometer on an Electron Probe Microanalyzer for Multidisciplinary Research and Hands-On Education at Fayetteville State University

该仪器项目由费耶特维尔州立大学（FSU）通过主要研究仪器（MRI）计划提出，旨在获得一台阴极发光光谱仪，该光谱仪将安装在FSU多用户设施中最先进的场发射电子探针微分析仪上。它将向北卡罗莱纳州、南卡罗来纳州和全国范围内的学术机构和联邦机构开放并支持研究。新仪器将用于材料表征，这将大大加强FSU的研究能力。新仪器将作为FSU培训少数民族学生的核心，为多元化和积极的STEM劳动力培养更多的少数民族和女性专业人士。此外，新的能力将作为一个开放的平台，与当地社区联系。该MRI项目支持了费耶特维尔州立大学的多个研究项目，包括纳米尺度和成分可控闪烁体纳米线的快速x射线检测，尺寸、尺寸和化学掺杂对二氧化铈纳米纤维发光的影响，离子注入中纳米晶体生长和堆积因子的基本控制机制，以及通过分析火成岩和碎屑锆石的分带而进行的岩浆和构造过程。通过这些原位研究，材料的微观结构、形状、尺寸、组成和发光性能可以在相同的样品中相互关联。

This instrumentation project, proposed by Fayetteville State University (FSU) through the Major Research Instrumentation (MRI) program is to acquire a cathodoluminescence spectrometer that will be installed on a state-of-the-art field-emission Electron Probe Microanalyzer at a multi-user facility at FSU. It will be open for access and support research at academic and federal agencies in North Carolina, South Carolina and nationwide. The new instrument will be used for materials characterization, which will significantly strengthen the research capabilities at the FSU. The new instrument will be used as a centerpiece for training minority students at FSU, producing more minority and female professionals for diversified and motivated STEM workforces. In addition, the new capability will serve as an open platform for outreach to local communities.This MRI project supports several research projects at Fayetteville State University as the fast X-ray detection using nanoscale size and composition-controllable scintillator nanowires, effects of dimensionality, size and chemical doping on luminescence of ceria nanofibers, fundamental mechanisms controlling growth and packing factor of nanocrystals in ion implantation, and magmatic and tectonic processes by analyzing zoning in igneous and detrital zircons. Through these in situ studies, the material microstructure, shape, size, composition and luminescence properties can be correlated from the same specimens.
