CRIF:MU: Acquisition of a Fluorimeter with Fluorescence Lifetime Capabilities

在化学研究仪器和设施：多用户计划(CRIF：MU)的支持下，奥斯汀得克萨斯大学化学系将获得一台能够测量荧光寿命的荧光仪。该奖项将提供一种仪器，供一大批研究人员使用，以研究各种分子和材料体系的基本光化学性质。需要研究的领域包括电致发光、新型光活性分子的合理设计、太阳能转换材料和激发态寿命的测量。荧光计是一种光谱仪，用来测量被光源提升到激发状态的样品发出的光的性质。这些发射光谱在广泛的频率和时间分辨率上进行测量，从而可以确定光激发态的性质及其寿命。这台仪器的配置将使化学内外各学科的大量用户都能使用它。该仪器将用于研究和本科生实验室课程，包括系新生研究计划。

With support from the Chemistry Research Instrumentation and Facilities: Multiuser Program (CRIF:MU), the Department of Chemistry at the University of Texas, Austin will acquire a fluorimeter with the capability of measuring fluorescence lifetimes. This award will provide an instrument to be used by a large group of researchers to investigate the fundamental photochemical properties of a variety of molecular and materials systems. The areas to be investigated include electroluminescence, the rational design of new photoactive molecules, materials for solar energy conversion and measurements of excited state lifetimes. Fluorimeters are spectrometers that measure the properties of the light emitted from a sample that has been promoted to an excited state by a light source. These emission spectra, measured over a wide range of frequencies and time resolutions, allow determination of the nature of photoexcited states and their lifetimes. The configuration of this instrument will make it accessible to a large number of users in a variety of disciplines both inside and outside of chemistry. The instrument will be used in research and undergraduate laboratory classes including the departmental Freshmen Research Initiative.
