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，旨在获得一个阴极发光光谱仪，该光谱仪将安装在FSU多用户设施的最先进的场发射电子探针显微分析仪上。它将开放供北卡罗来纳州、南卡罗来纳州和全国的学术和联邦机构访问和支持研究。新仪器将用于材料表征，这将大大加强FSU的研究能力。新的工具将被用作培训少数民族学生在FSU的核心，生产更多的少数民族和女性专业人士的多元化和积极的干劳动力。此外，新的能力将作为一个开放的平台，推广到当地社区。这个MRI项目支持费耶特维尔州立大学的几个研究项目，如使用纳米尺寸和成分可控的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，控制离子注入中纳米晶体生长和填充因子的基本机制，岩浆作用和构造作用。通过这些原位研究，材料的微观结构，形状，尺寸，成分和发光性能可以从相同的标本相关联。

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.
