Spectroscopically Determined Excited State Properties and Photochemical Reactivities of Inorganic Compounds

该项目由化学学部实验物理化学项目资助，Zink将对金属和半导体光沉积无机分子前驱体的激发态和反应性进行研究。对一系列金属有机分子进行吸收、发射、共振拉曼光谱以及气相作用光谱和共振增强多光子电离实验。这些化合物的基本光谱和光化学性质将用于建立沉积过程和纳米结构形成的最佳参数。气态金属有机化合物的薄膜沉积和纳米结构的形成取决于分子的光谱和光化学性质的知识。这项研究的目的是为了更好地理解这些特性，以促进薄膜、光刻和直接写入单元的高效制造，在制造三维电路和光子晶体方面具有潜在用途的三维结构的生产，以及在多孔和模板材料中生产纳米颗粒。这项研究将由学生进行，这些学生因此将接受训练，为进入科学/技术工作队伍做准备。

In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Zink will conduct research on the excited electronic states and reactivities of inorganic molecular precursors for photodeposition of metals and semiconductors. Absorption, emission and resonance Raman spectroscopies as well as gas phase action spectra and resonance enhanced multiphoton ionization experiments will be performed on a series of metal organic molecules. The basic spectroscopic and photochemical properties of these compounds will be used to establish optimum parameters for deposition processes and formation of nano-strutures.Thin film deposition and formation of nano-structures from gaseous metal organic compounds depend on the knowledge of the spectroscopic and photochemical properties of the molecules. This research is directed to bring about a better understanding of these properties in order to facilitate efficient fabrication of thin films, lithography and direct writing units, the production of three dimensional structures with potential use in making three-dimensional circuits and photonic crystals, and the production of nanoparticles in porous and templated materials. The research will be done with students who thereby will receive training in preparation for entering the scientific/technological workforce.
