Exciton Dynamics and Laser Action in Conducting Polymers

这是犹他大学物理系教授Z. Vardeny提出的建议，描述了半导体聚合物作为新型激光材料的研究前景。这项研究将由一个重点研究小组的成员进行，该小组将调查这些材料的各种特性。这些半导体聚合物体系还没有得到充分的了解，目前对实验结果及其解释存在重大争议。本研究将试图为PPV和相关聚合物的放大发射来源的关键问题提供答案。本研究将讨论超荧光、超辐射和放大自发辐射的作用。犹他小组将着手解决这些问题，并将通过仔细进行的实验和理论分析，从而有助于消除误解和误解。如果固态有机激光器能够以技术可靠的方式生产出来，这项基础研究有可能产生巨大的影响。犹他大学物理系的Z.

9732820 Vardeny This proposal by Professor Z. Vardeny of the Department of Physics of the University of Utah describes research on semiconducting polymers which offer promise as new lasing materials. The research will be conducted by members of a Focused Research Group which will investigate the various properties of these materials. These systems of semiconducting polymers are not yet sufficiently well understood and there is at present significant controversy about the results of experiments and their interpretation. This research will attempt to provide answers to critical questions on the origin of the amplified emission from PPV and related polymers. The roles of superfluorescence, superradiance, and amplified spontaneous emission will be addressed in this research. The Utah group will attack these problems and will thereby contribute to clearing up misunderstandings and misinterpretations through carefully conducted experiments and theoretical analyses. This basic research has the potential of making a great impact if solid state organic lasers can be produced in a technologically reliable manner. %%% This proposal by Professor Z.
