Fluorescence is an important photophysical phenomenon that can be observed for various materials, ranging from small organic molecules, inorganic complexes to synthetic polymers, biomacromolecules, and nanoparticles. Understanding of fluorescence properties is a vital and powerful approach to investigate structural, electronic, and chemical properties at the molecular level. As such, the technique of fluorescence spectroscopy has been extensively employed in scientific and engineering research. For example, certain fluorescent organic and inorganic compounds can be rationally designed to act as chemosensors and biosensors capable of recognizing and quantifying environmentally and biologically important chemical species with ultra-high sensitivity and selectivity. Fluorescent proteins can be introduced into living cells to label and track biomolecules. Various organic conjugated polymers and functionalized nanoparticles with high fluorescence efficiencies can be applied as active components in the fabrication of advanced light emitting devices (LEDs). Indeed, fluorescent materials have play a central role in modern science and technology, while the studies of these materials heavily reply on advanced techniques of fluorescence spectroscopic analyses. We plan to purchase a spectrofluorometer, which will be an essential research tool for investigating various fluorescence properties. At Memorial University, there are many research programs requiring an on-campus access to such equipment. In particular, researchers in the fields of materials chemistry, environmental engineering, and processing engineering require fluorescence spectroscopic measurements to advance their programs of research. Unfortunately, a fully functional spectrofluorometer is not available at Memorial University. Access to this important research tool will greatly benefit our research and HQP training programs. In the long term, the proposed spectrofluorometer will offer a technical platform to strengthen cutting-edge research programs, foster new research collaborations, and extensively train HQP in multiple disciplines.

荧光是一种重要的光物理现象，可以观察到各种材料，从小有机分子，无机络合物到合成聚合物，生物乳清分子和纳米颗粒。了解荧光性能是研究分子水平上的结构，电子和化学特性的一种至关重要的方法。因此，荧光光谱技术已广泛用于科学和工程研究。例如，某些荧光有机和无机化合物可以合理设计为化学传感器和生物传感器，能够识别和量化具有超高敏感性和选择性的环境和生物学上重要的化学物种。荧光蛋白可以引入活细胞中以标记和跟踪生物分子。各种有机共轭聚合物和具有较高荧光效率的功能化纳米颗粒可以在制造高级光发射器件（LED）中作为活性成分。实际上，荧光材料在现代科学和技术中起着核心作用，而对这些材料的研究对荧光光谱分析的先进技术进行了大量答复。 我们计划购买SpectroFluorometer，这将是研究各种荧光性能的必不可少的研究工具。在纪念大学，有许多研究计划需要校园内使用此类设备。特别是，材料化学，环境工程和加工工程领域的研究人员需要荧光光谱测量以推进其研究计划。不幸的是，纪念大学没有功能齐全的光谱仪。访问此重要的研究工具将极大地使我们的研究和HQP培训计划受益。从长远来看，拟议的SpectroFluorometer将提供一个技术平台，以增强尖端研究计划，培养新的研究合作，并在多个学科中广泛培训HQP。
