MRI: Acquisition of Luminescence Lifetime Instrumentation by a Partnership of Maine Undergraduate Institutions for Research and Student Training

在重大研究仪器(MRI)计划的这一奖励下，新英格兰大学的化学和物理系将获得一台用于测量发光寿命的荧光分光计。该仪器的主要研究应用分为三大类：(1)设计、合成和表征具有特殊发光特性的新型金属化合物和类金属化合物；(2)表征“可调谐”发光的稀土离子-异质双金属双氰化物的光物理性质；(3)探索发光铂族分子的光物理和光化学。发光寿命光谱仪测量从被光源提升到激发状态的样品发出的光的衰减时间。这提供了对发光材料(如有机发光二极管(OLED)和化学传感器)中能量传递和损失的机制的洞察。该仪器将用于本科生的研究和实验室课程。这是一个合作奖项。该仪器将由新英格兰大学(UNE)、南缅因州大学(USM)和鲍登学院的研究人员共享。

With this award from the Major Research Instrumentation (MRI) program, the Department of Chemistry and Physics at the University of New England will acquire a spectrofluorometer to measure luminescence lifetimes. The primary research applications of the proposed instrument fall into three broad categories: (1) the design, synthesis, and characterization of novel metalloles and metallole-like compounds that display unusual luminescence characteristics, (2) characterization of the photophysical properties of "tunable" luminescent lanthanide ion-heterobimetallic dicyanides, and (3) the exploration of the photophysics and photochemistry of luminescent platinum group molecules. Luminescence lifetime spectrometers measure the decay time of the light emitted from a sample that has been promoted to an excited state by a light source. This provides insight into the mechanisms of energy transfer and loss in materials that emit light such as organic light emitting diodes (OLEDs) and chemical sensors. The instrument will be used in research and laboratory classes by undergraduate students. This is a collaborative award. The instrument will be shared by investigators at the University of New England (UNE), the University of Southern Maine (USM), and Bowdoin College.
