MRI: Acquisition of a Transient Absorption Spectrometer

根据主要研究仪器（MRI）和化学研究仪器和设施（CRIF）项目的这份合同，佛罗里达州立大学将获得一台瞬态吸收光谱仪。瞬态吸收（TA）光谱学是一种强大的技术，用于监测样品（即颜色）在闪光激发后随时间的吸光度变化。虽然纳秒瞬态吸收技术并不新鲜，但它在未开发研究领域的应用可以在分子和材料的光物理性质方面产生重要的结果。这些结果将直接影响太阳能转换、光动力治疗、光催化、固态照明和金属离子传感等应用。拟议文书的用户友好性质将改善各级学生的奖学金、教育和培训。TA光谱仪将向该地区的所有学术机构开放，包括少数民族服务机构和妇女？美国大学以及工业合作伙伴。该提案旨在加强研究，特别是在以下领域：(a)研究分子和材料的光物理性质；(b)深入了解电子/能量转移；(c)研究激发态猝灭；(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.
