SNM: Scalable Volume-NanoManufacturing of Unique Nanoparticles by Nano-templated Printing, Deposition, and Exfoliation for Energy and Bio/Chemical Sensing

为了在给定的应用中具有最佳的性能，纳米颗粒必须具有均匀的尺寸和精确的形状、结构和组成。这一可扩展纳米制造（SNM）奖项支持一种创新方法，以在制造新型能量转换荧光粉纳米颗粒时实现这种均匀性。这种方法被称为“通过模板可剥离沉积的纳米打印”（n- printing），与传统的化学合成有着根本的不同。这种新方法使用模板，有可能生产出广泛的纳米颗粒类型，适用于广泛的领域和行业，包括生物/化学传感、固态照明、显示器、电池和燃料电池。这项研究的成功将有利于美国在纳米技术方面的竞争力和领导地位，并帮助美国工业，产生重大的经济影响。为了克服纳米颗粒制造中的关键挑战，这种新方法n- print通过使用模板来限制材料沉积/反应来制造纳米颗粒（NPs），从而调节材料（因此最终的NP）的形状和位置，而不是“自由形式”的反应；n- print也为沉积方法、材料选择、加工/反应条件和顺序开辟了广泛的新可能性。因此，n- print提供了许多新的方法来制造具有独特形状，结构和成分（因此性质）的NPs，这是目前方法无法实现的。因此，n- print可以用于广泛的新型纳米颗粒。该项目将重点关注n- print在新型NPs中的应用，以实现高效的上下能量转换，并将采取一种整合广泛学科和知识的方法。

To have the best possible performance in a given application, nanoparticles must be manufactured with uniform size and precise shape, structure and composition. This Scalable NanoManufacturing (SNM) award supports an innovative approach to attaining such uniformity in the manufacturing of a new class of energy conversion phosphor nanoparticles. This approach, termed "nanoprint by templated exfoliateable deposition" (n-PrinTED), is fundamentally different from traditional chemical synthesis. The new method uses a template and potentially enables the production of a broad range of nanoparticle types applicable to a wide range of fields and industries, including bio/chemical sensing, solid state lighting, displays, batteries, and fuel cells. The success of the research will benefit U.S. competitiveness and leadership in nanotechnology and aid U.S industry, leading to significant economic impact.To overcome the key challenges in nanoparticle fabrication, this new method, n-PrinTED, fabricates nanoparticles (NPs) by using a template to restrict material deposition/reaction, which regulates the materials' (hence the final NP's) shape and location, rather than a "free-form" reaction; and n-PrinTED also opens up a broad range of new possibilities in deposition methods, materials choices, and processing/reaction conditions and sequences. Therefore, n-PrinTED offers many new ways to fabricate NPs with unique shapes, structures, and compositions (hence properties) that are unachievable by current methods. n-PrinTED can thus be used for a broad range of new nanoparticles. The project will focus on the application of n-PrinTED in new NPs for efficient up/down conversion of energy and will take an approach that integrates a broad range of disciplines and knowledge.
