Research grade spectrofluorometer

萨斯喀彻温大学的物理化学和材料科学研究人员绝对需要获得性能可靠的研究级荧光分光光度计。荧光和磷光光谱通常用于表征样品中电子激发态的结构和弛豫动力学，范围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级材料。测量包括：高分辨率的发射和激发光谱;弱发射物种的量子产率;发射各向异性;低温下的荧光和磷光实验; FRET和电子转移的激发态淬灭。所要求的荧光分光光度计将作为一个多用途，多用户设施，以支持化学系的五名NSERC资助的教师和大约20名学生，PDF和RA在他们的研究小组的研究。它还将作为一次性实验的部门工具，由其他人在萨斯喀彻温大学更大的研究社区进行。

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.
