The objective of this proposal is to use inclusion chemistry to synthesize and characterize electro-optic materials which can be fine tuned and switched as nanocomposites. The preliminary research has demonstrated our ability to define the compositional phase space of an extensive class of materials which have the same topology as one of the premier nonlinear optic crystals known, KTP. The phase space of a second inclusion structural family, ABCO4, is being explored and has been shown to contain members with optical windows to 0.2 um and large SHG coefficients. Reversible gas phase adsorption, guest/host interace chemistry, and solid state substitution chemistry are being used to modify electro-optic behavior with respect to SHG and phase matching. Exploratory research using a variety of synthetic techniques is proposed in our search for new nonlinear optic inclusion hosts. A second objective of this research is to examine the nonlinear optic response as a function of externally induced atomic displacements by applied electric field, temperature, and pressure. Exploratory synthesis into new structural types will make use of the structure/property relationships determined in the above studies.

该提案的目的是利用包合物化学来合成和表征可以微调和转换为纳米复合材料的电光材料。 初步研究表明，我们有能力定义多种材料的组成相空间，这些材料与已知的首要非线性光学晶体之一 KTP 具有相同的拓扑结构。 第二个夹杂结构族 ABCO4 的相空间正在探索中，并已被证明包含具有 0.2 um 光学窗口和大 SHG 系数的成员。 可逆气相吸附、客体/主体界面化学和固态取代化学被用来改变二次谐波和相位匹配方面的电光行为。 在寻找新的非线性光学夹杂物主体的过程中，我们提出了使用各种合成技术的探索性研究。 这项研究的第二个目标是检查非线性光学响应作为施加电场、温度和压力引起的外部原子位移的函数。 新结构类型的探索性合成将利用上述研究中确定的结构/性质关系。
