Non-Technical AbstractNew materials - chemical compounds - are at the core of advanced technologies, such as fuel cells, blue-ray DVD players, smart phones, and lasers. The challenge lies in not only discovering a new material, but also understanding its technologically relevant properties. If advancements in technology are to occur - and such advancements are critical if the United States is to remain the leader in science - the discovery and understanding of new materials are critical. This fundamental research project, supported by the Solid State and Materials Chemistry Program in the Division of Materials Research, involves the design, discovery, and crystal growth of new materials for advanced technologies. Specifically, the research team is focused on new materials for laser applications. The aim is to discover materials that enable lasing technologies, i.e. coherent radiation, in the ultraviolet and deep-ultraviolet wavelengths - below 300 nanometers. Coherent radiation in these wavelength ranges is critically needed for advanced technologies and devices, and the proposed materials will positively impact these technologies. Finally, there will be a specific emphasis on recruiting underrepresented groups in STEM to the research group as the University of Houston is designated as a Hispanic-Serving Institution (HSI).Technical AbstractThis research project, supported by the Solid State and Materials Chemistry Program in the Division of Materials Research, involves the design, synthesis, structure, functional property characterization, and structure-property relationships of new functional inorganic materials - mixed alkali and alkaline earth borate oxyfluorides and mixed alkali and alkaline-earth metal nitrates - for ultraviolet (UV) and deep-ultraviolet (DUV) nonlinear optical (NLO) applications. An ongoing challenge in inorganic solid-state chemistry is the ‘rational design’ of new materials - to design and synthesize precise stoichiometries that will exhibit specific, and ideally, technologically important properties. Meeting this challenge not only requires synthetic expertise, but also a deep understanding of the various bonding and crystal chemistry requirements for the desired physical property. To further this understanding, the research team at the University of Houston not only synthesizes new materials, but also develops structure-property relationships. In addition to bulk phase synthesis, the growth of large, centimeter size, crystals is planned. Large single crystals are crucial in order to thoroughly investigate and understand the functional properties. Top-seeded solution growth methods can be employed for the crystal growth. The materials are characterized structurally by X-ray diffraction - powder and single crystal - and physical property measurements will include, thermogravimetric analysis, differential scanning calorimetry, and second-harmonic generation measurements. Through this holistic approach - synthesis, crystal growth, characterization, and structure-property relationships - the research team aims to profoundly advance the field.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要新材料-化合物-是先进技术的核心，如燃料电池，蓝光DVD播放器，智能手机和激光。挑战不仅在于发现新材料，而且还在于了解其技术相关特性。如果技术要取得进步--如果美国要保持科学的领先地位，这种进步是至关重要的--对新材料的发现和理解是至关重要的。该基础研究项目由材料研究部的固态和材料化学计划支持，涉及先进技术新材料的设计，发现和晶体生长。具体而言，研究团队专注于激光应用的新材料。其目的是发现能够在紫外和深紫外波长（低于300纳米）实现激光技术（即相干辐射）的材料。这些波长范围内的相干辐射是先进技术和设备所迫切需要的，而拟议的材料将对这些技术产生积极影响。最后，将特别强调招募STEM中代表性不足的群体加入研究小组，因为休斯顿大学被指定为西班牙裔服务机构（HSI）。技术摘要本研究项目由材料研究部的固态和材料化学计划支持，涉及设计，合成，结构，功能性质表征，以及新型功能无机材料-混合碱金属和碱土金属硼氧氟化物以及混合碱金属和碱土金属硝酸盐-在紫外（UV）和深紫外（DUV）非线性光学（NLO）应用中的结构-性能关系。无机固态化学的一个持续挑战是新材料的“合理设计”-设计和合成精确的化学计量，将表现出特定的，理想的，技术上重要的性能。应对这一挑战不仅需要合成专业知识，还需要深入了解所需物理性能的各种键合和晶体化学要求。为了进一步理解这一点，休斯顿大学的研究团队不仅合成了新材料，还开发了结构-性能关系。除了体相合成外，还计划生长厘米级的大晶体。为了彻底研究和理解功能特性，大单晶至关重要。顶部籽晶溶液生长方法可用于晶体生长。这些材料的结构特征是X射线衍射-粉末和单晶-和物理性能测量将包括，热重分析，差示扫描量热法，和二次谐波产生测量。通过这种整体方法-合成，晶体生长，表征和结构-性质关系-研究团队旨在深入推进该领域。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
