9875765DexheimerIn this research supported by a CAREER Award the PI will study the dynamics of electronic excitations in one-dimensional materials, such as platinum ethylenediamine complexes. Specific issues addressed are the dynamics of the formation of photoinduced defect states, the time evolution of the electronic excitations, and the transport properties of the excitations. Femtosecond optical techniques, including ultrafast transient absorption, impulsive vibrational excitation, and photon echo measurements will be employed. Strong emphasis is given to the improvement of the undergraduate curriculum in optical physics by developing state of the art laboratory activities. The PI will also develop and implement plans for improving the retention and professional success of women students in science and engineering.%%%In this project supported by a CAREER award the PI will study the interactions between electrons and the lattice of solid metal-organic compounds by using several ultra-fast optical techniques. The research will engage graduate and undergraduate students and prepare them for careers in areas of advanced science and technology for the 21st Century. Strong emphasis will be given to the improvement of the undergraduate curriculum in optical physics, an area which is now, and for many years to come of great importance to basic science and technology. Plans will be developed and implemented for improving the retention and professional success of women students in science and engineering. ***

在这项由CAREER奖支持的研究中，PI将研究一维材料（如铂-乙二胺配合物）中的电子激发动力学。讨论的具体问题是光致缺陷态形成的动力学，电子激发的时间演化，以及激发的输运性质。飞秒光学技术，包括超快瞬态吸收、脉冲振动激发和光子回波测量将被采用。重点是通过发展先进的实验室活动来改进光学物理本科课程。PI还将制定和实施计划，以提高女学生在科学和工程领域的留用率和专业成就。在这个由CAREER奖支持的项目中，PI将使用几种超快光学技术研究电子与固体金属有机化合物晶格之间的相互作用。这项研究将吸引研究生和本科生，为他们在21世纪的先进科学和技术领域的职业生涯做好准备。在今后的许多年里，光学物理在基础科学和技术中都具有重要的地位。将制定和执行计划，以提高女学生在科学和工程领域的留用率和专业成就。* * *
