SGER: Graded Optical Index Materials

9978584 Bhalla在其微观结构中发生“连续”变化的功能梯度材料（FGM）可用于多种电气和机械应用。 为了拓展功能梯度材料在光学竞技场中的应用，要求材料在微米到纳米尺度范围内具有梯度结构-性能关系。 在这个SGER提案中，PI建议使用混合氧化物材料的纳米级有序行为，从而定制和分级这类特殊材料的光电性能。 在特定的加热循环下，材料的有序度会发生变化，从而影响材料的光电性能。 几种弛豫型和有序-无序型材料将被测试以实现拟议研究的目标。这一想法是新颖的，以前没有被测试过，以生产高度有用和需要的光学梯度折射率陶瓷或单晶材料。拟议工作的范围确实属于新的和高风险的研究类别。 如果成功，设想这种材料在光电子领域的若干新应用。

9978584BhallaFunctionally graded materials (FGM) with 'continuous' changes occurring in their microstructure are useful for several electrical and mechanical applications. In order to expand the usefulness of FGM in optical arena the materials should have graded structure-property relationship on the micro to nanoscale range. In this SGER proposal the PI has suggested to use the nanoscale-ordering behavior of the mixed oxide materials and thus tailoring and grading the optoelectronic properties of this special class of materials. Under special heating cycle the degree of orderedness in the material can be varied which consequently will also influence the optoelectronic properties of materials. Several relaxor and order-disorder type materials will be tested for achieving the goals of the proposed research.The idea is novel and has not been tested before to produce the highly useful and needed optical graded refractive index ceramics or single crystal materials.The scope of the proposed work does fall in the new and high-risk category of research. If it is successful several new applications of such materials are envisaged in the optoelectronic area.***
