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.

在这个由化学部实验物理化学计划资助的项目中，Zink将对金属和半导体光沉积的无机分子前体的激发电子态和反应性进行研究。对一系列金属有机分子进行吸收光谱、发射光谱、共振拉曼光谱、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确定沉积过程和纳米结构形成的最佳参数。薄膜沉积和从气态金属有机化合物形成纳米结构取决于分子的光谱和光化学性质的知识。本研究旨在更好地了解这些特性，以促进薄膜，光刻和直写单元的有效制造，具有潜在用途的三维结构的生产，在制造三维电路和光子晶体，以及在多孔和模板材料中生产纳米颗粒。这项研究将与学生一起进行，他们将接受培训，为进入科学/技术劳动力队伍做准备。
