Engineering Research Equipment: Luminescence Spectrometer for Polarized Light Emission from Liquid Crystalline Glassy Films

摘要/ ABSTRACT摘要：为支持nsf资助的关于玻璃形成晶体的项目，提供了一个发光光谱仪（LS-50B, Perkin-Elmer）。所要求的仪器支持的研究的中心主题是有序固体薄膜的偏振光发射。具体地说，嵌入在非荧光向列和手性向列液晶玻璃宿主中的光源的线性和圆偏振发光将被实验表征。在一个理论框架内，通过解释观测到的偏振发射程度，将提供全面的理解，在这个理论框架内，光在结构介质中的吸附、产生和传播都被考虑在内。除了对这些复杂光学过程的新的基本见解外，该结果有望促进光学和光电子学的技术进步。目前，六名博士后和材料科学博士研究生以及两名化学工程本科生将受益于发光光谱仪作为光电材料研究的一部分。

ABSTRACT CTS-9811172 Shaw H. Chen/U. of Rochester Equipment funds are provided for a luminescence spectrometer (LS-50B, Perkin-Elmer) to support an NSF-funded project on glass-forming crystals. The central theme of the research to be supported by the requested instrument is polarized light emission from ordered solid films. Specifically, linearly and circularly polarized luminescence from light-emitters embedded in nonfluorescent nematic and chiral-nematic liquid crystalline glassy hosts will be experimentally characterized. Comprehensive understanding will be furnished through interpretation of the observed degrees of polarized emission within the framework of a theory in which the adsorption, generation, and propagation of light in structures media are all accounted for. In addition to new fundamental insight into these complex optical processes, the results are expected to promote technological advances in optics and optoelectronics. At the present time, group of six post-doctoral and Materials Science PhD students plus two Chemical Engineering undergraduate students will benefit from working with luminescence spectrometer as part of optoelectronic materials research.
