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.

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，旨在购买一台阴极发光光谱仪，该光谱仪将安装在多中心的最先进的场发射电子探针显微分析仪上。 FSU 的用户设施。它将向北卡罗来纳州、南卡罗来纳州和全国的学术和联邦机构开放并支持研究。新仪器将用于材料表征，这将显着增强佛罗里达州立大学的研究能力。新工具将用作佛罗里达州立大学少数族裔学生培训的核心，为多元化和积极进取的 STEM 劳动力培养更多的少数族裔和女性专业人士。此外，新功能将作为一个开放平台，向当地社区进行推广。该 MRI 项目支持费耶特维尔州立大学的多个研究项目，例如使用纳米级尺寸和成分可控的闪烁体纳米线进行快速 X 射线检测、维度效应、尺寸和化学掺杂对二氧化铈纳米纤维发光的影响，离子注入中控制纳米晶体生长和堆积因子的基本机制，以及通过分析分区的岩浆和构造过程火成锆石和碎屑锆石。通过这些原位研究，可以将同一样本的材料微观结构、形状、尺寸、成分和发光特性关联起来。
