MRI: Acquisition of a Transient Absorption Spectrometer

有了这项来自主要研究仪器（MRI）和化学研究仪器和设施（CRIF）计划的奖励，佛罗里达州立大学将获得瞬态吸收光谱仪。瞬态吸收（TA）光谱是一种监测样品吸光度变化的强大技术（即，例如，颜色）在闪光激发后相对于时间的变化。虽然纳秒瞬态吸收技术并不新鲜，但将其应用于未探索的研究领域可以产生关于分子和材料的物理性质的重要结果。这些结果将直接影响太阳能转换、光动力疗法、光电子学、固态照明和金属离子传感等应用。拟议的工具方便用户，将改善各级学生的奖学金、教育和培训。TA光谱仪将向该区域所有学术机构开放，包括为少数群体服务的机构，妇女？该提案旨在加强研究，特别是在以下领域：（a）研究分子和材料的物理特性;（B）深入了解电子/能量转移;（c）研究激发态淬灭;（d）研究光化学反应;（e）研究激发扩散和电荷分离。

With this award from the Major Research Instrumentation (MRI) and Chemistry Research Instrumentation and Facilities (CRIF) programs, Florida State University will acquire a transient absorption spectrometer. Transient absorption (TA) spectroscopy is a powerful technique for monitoring the change of absorbance of light by a sample (i. e., color) with respect to time after excitation by a flash of light. While nanosecond transient absorption technique is not new, its application to unexplored areas of research can yield important results on the photophysical properties of molecules and materials. These results will directly impact applications such as solar energy conversion, photodynamic therapy, photocatalysis, solid-state lighting, and metal ion sensing. The user-friendly nature of the proposed instrument will improve the scholarship, education and training of students at all levels. The TA spectrometer will be open to all academic institutions in the region, including minority-serving institutions, and women?s colleges as well as industrial partners.The proposal is aimed at enhancing research especially in areas such as (a) studying photophysical properties of molecules and materials; (b) providing insight into electron/energy transfer; (c) investigating excited state quenching; (d) studying photochemical reactions; and (e) investigating excition diffusion and charge separation.
