Synthesis and Characterization of New Rare Earth Metal Main Group Metal Materials

该项目基于一组可用的构建块来预测固体族中的化学-结构关系。基本工具将能够广泛应用于任何一组构建模块和连接单元，无论它们是稀土金属和主基团阴离子还是其他中性或离子构建模块。材料合成的三个相互关联的领域将被讨论，重点是针对特定的稀土金属主族金属材料开发成分相图，包括稀土金属铜酸盐、稀土金属铜酸盐和稀土金属铜酸盐的四元相空间。一系列的化学配方将会被测试，这些配方表明产品可能含有目标成分。在某些情况下，这些公式可以预测相关产物的空间群对称性。该项目为合成新型固体化合物提供了指导方针，并为理解结构家族如何相互关联以及这些家族如何表现出独特的光学和电子特性提供了指导方针。该项目更广泛的影响包括培养材料设计和化学合成科学领域的博士后学者、研究生和本科生。科罗拉多州立大学正在开发一个新的跨学科材料化学研究生课程，这在落基山脉地区是独一无二的

This project addresses the prediction of chemical-structural relationships in a family of solids based on a set of available building blocks. The fundamental tools will be able to be broadly applied to any set of building blocks and connecting units, whether they are rare-earth metals and main group anions or other neutral or ionic building blocks. Three interrelated areas of materials synthesis will be addressed with an emphasis on developing composition phase diagrams for targeting specific rare-earth metal main group metal materials to include quaternary phase space of rare-earth metal chalcopnictates, quaternary rare-earth metal chalcotetrelates, and quaternary rare-earth metal chalcotrielates. A series of chemical formulae that suggest products with targeted compositions are possible will be tested. These formulae, in some cases, can predict the space group symmetry of the related products. %%%This project is providing guidelines for the synthesis of new classes of solid compounds, and guidelines for understanding how families of structures are interrelated and how those families exhibit unique optical and electronic properties. The broader impacts of the project include the training of post doctoral scholars, graduate students and undergraduate students, in the science of materials design and chemical synthesis. A new interdisciplinary Materials Chemistry graduate program is being developed at Colorado State University that is unique in the Rocky Mountain region.***
