Research grade spectrofluorometer

对于萨斯喀彻温大学物理化学和材料科学的研究人员来说，获得研究级荧光分光光度计并获得可靠的性能是绝对必要的。荧光和磷光光谱通常被用来表征样品中电子激发态的结构和驰豫动力学，从气相中的小分子到溶液中的金属卟啉，再到固相中的量子点和纳米材料。测量包括：高分辨率的发射光谱和激发光谱；弱发射物种的量子产额；发射的各向异性；低温下的荧光和磷光实验；FRET和电子转移猝灭激发态。所要求的荧光分光光度计将作为一个多用途、多用户的设施，以支持NSERC资助的化学系五名教员和他们研究小组中的大约20名学生、PDF和RA的研究。它还将作为一个部门工具，供萨斯喀彻温大学更大的研究社区中的其他人进行一次性实验。

Access to and reliable performance of a research grade spectrofluorometer is an absolute imperative for researchers in physical chemistry and materials science at the University of Saskatchewan. Fluorescence and phosphorescence spectroscopy is used routinely to characterize the structures and relaxation dynamics of electronic excited states in samples ranging from small molecules in the gas phase to metalloporphyrins in solution to quantum dots and nanoscale materials in the solid phase. Measurements include: emission and excitation spectra at high resolution; quantum yields of weakly emitting species; emission anisotropies; fluorescence and phosphorescence experiments at cryogenic temperatures; excited state quenching by FRET and electron transfer. The spectrofluorometer requested will serve as a multipurpose, multi-user facility to support the research of five NSERC-funded faculty members in the Department of Chemistry and approximately 20 students, PDFs and RAs in their research groups. It will also serve as a Departmental tool for one-off experiments to be conducted by others in the larger University of Saskatchewan research community.
