0735911EilersThis project seeks to enhance the sensitivity and applicability of scintillator materials for nuclear threat detection. The project will investigate the effect of adding metallic nanoparticles to high density scintillator materials. The aim is to investigate whether the addition of these nanoparticles can simultaneously increase the quantum efficiency and decrease the decay time of the scintillator. If this can be achieved it could lead to higher quality detectors with enhanced applicability for homeland security and other applications. The broader impacts of the proposed research lie in the development of an improved type of scintillator detector, with improved count rate and energy resolution. In addition a postdoctoral fellow and undergraduate student will be involved in the research.

0735911Eilers这个项目旨在提高闪烁体材料对核威胁检测的敏感性和适用性。该项目将研究将金属纳米颗粒添加到高密度闪烁体材料中的效果。目的是研究这些纳米颗粒的添加是否可以同时提高量子效率并减少闪烁体的衰减时间。如果可以实现这一目标，则可以导致更高质量的探测器，并且对国土安全性和其他应用程序的适用性增强。拟议的研究的更广泛的影响在于开发改进的闪烁体检测器类型，并提高了计数速率和能量率。 此外，博士后研究员和本科生将参与研究。
