项目摘要

The proposed research is directed towards the synthesis, modification, and study of structure/property relationships of nonlinear optic inclusion materials. Three thrusts are considered: 1) Exploratory synthesis of new nonlinear optic active host framework materials; 2) Nonlinear optic active host systems generated by selectively induced anisotropic stress coupled with compositional driven phase instabilities; and 3) Nonlinear optic nanocomposites synthesized by the self-organization and alignment of hyperpolarizable atomic and molecular entities on the surface and within the channels of polar inorganic molecular sieves. Exploratory synthesis using hydrothermal, flux, solid state, sol gel and thin film techniques are proposed along with the use of guest/host ion exchange, sorption, and solid state substitution chemistry to modify nonlinear optic behavior. A second objective of this research is to examine atomic displacements externally induced by temperature and pressure and their relation to elecro- optic related phase changes. Inclusion guest and host chemistry can be used to control second harmonic generation response over a wide range. The chemistry and characterization needed to better understand this relationship will be studied and theoretically modelled during the proposed funding period and applied to the exploratory synthesis of new nonlinear optic materials.

所提出的研究是针对合成，改性和结构/性能关系的研究非线性光学包体材料考虑了三个推力： 1)新型非线性光学活性基质的探索性合成非线性光学活性主体体系由选择性诱导的各向异性应力产生，成分驱动的相位不稳定性;以及3）非线性光学自组织取向合成纳米复合材料超极化的原子和分子实体和在极性无机分子筛的通道内。使用水热、助熔剂、固态、溶胶的探索性合成凝胶和薄膜技术被提出沿着使用客体/主体离子交换、吸附和固态取代化学修饰非线性光学行为。第二个目的这项研究的一个目的是检查原子的外部位移，温度和压力的影响，以及它们与电光学相关的相位变化包合主客体化学可用于控制二次谐波产生响应范围很广。化学和表征需要更好地理解这种关系将被研究和理论上在拟议供资期间模拟，并适用于探索性合成新型非线性光学材料。
