New Solids for Making and Manipulating Light

这项工作的目标是制备和研究新的无机固体，它们将作为非线性光学（NLO）材料或作为激光和其他发光离子的宿主，并发展对控制物理性质的因素的理解。研究了一类新的非中心对称硼酸铝的光学和热性质、离子电导率和晶体结构。含碱土金属原子的新型氟硅酸盐的生成将为实现具有独特氧阴离子氧化环境的新宿主提供机会，以取代发光离子。详细了解晶体结构与镓和铟离子的光学发射特性之间的关系将通过光学、光电导和核磁共振研究几种掺杂和化学计量化合物的粉末和单晶形式发展。该项目的重点是制备和表征新型晶体无机材料，这些材料表现出非线性光学特性或具有作为发光离子宿主的潜力，包括可以诱导激光的离子。具有操纵光能力的材料的设计和合成在各种努力中都很重要，包括电信，激光的医疗应用，汽车防撞系统和军事系统。＊＊＊

9617031 Keszler The objectives of this work are to prepare and study new inorganic solids that will function as nonlinear optical (NLO) materials or as hosts for laser and other luminescent ions and to develop an understanding of the factors that control physical properties. Optical and thermal properties, ionic conductivity's, and crystal structures of a new family of noncentrosymmetric aluminum borates will be examined. The generation of new silicate fluorides containing alkaline-earth metal atoms will provide opportunities to realize new hosts having unique oxoanion oxide environments for substitution of luminescent ions. A detailed understanding of the relationships between crystal structure and optical emission characteristics of the gallium and indium ions will be developed through optical, photoconductivity, and nuclear magnetic resonance studies of several doped and stoichiometric compounds in powder and single-crystal form. %%% The focus of this project is on the preparation and characterization of novel, crystalline inorganic materials that exhibit nonlinear optical properties or have the potential to function as hosts for luminescent ions, including ones that can be induced to laser. The design and synthesis of materials with the ability to manipulate light is important in a variety of endeavors, including telecommunications, medical applications of lasers, collision avoidance systems for automobiles, and military systems. ***
