This Small Business Innovation Research Program (SBIR) Phase I project will allow the optimization of the novel Plasma-shell technology for incorporation into a large area Ultra-Violet (UV) emitting tile for use in germicidal applications. Plasma-shells are small gas encapsulating devices that emit light when energized. This research will focus on improving the transmissivity of the hermetic outer wall of the Plasma-shell to improve overall efficiency. Plasma-shells are lightweight, low cost and extremely rugged devices. The Plasma-shell is the only UV technology that can offer ultra large area completely diffuse (Lambertian) light output, which is very useful for conventional UV sterilization. These attributes will have an even greater impact when used to energize TiO2 in a photocatalytic process. UV activated TiO2 is a powerful catalyst that can be used in the breakdown of chemicals and the destruction of pathogens in contaminated water. However, the efficient scaling of the TiO2 photocatalytic process is dependent on efficiently coupling the UV light source to the TiO2. The envisioned large area low cost Lambertian output from an array of Plasma-shells will provide a previously unavailable lighting option that will make possible the efficient scaling of a TiO2 based water purification system. The broader impact/commercial potential of this project includes a novel technology that will provide a large area, efficient and low cost Ultra-Violet (UV) light source. This research has high commercial potential as the end product will be more efficient, environmentally safe, rugged and more cost effective than the current state-of-the-art UV light sources. Under this SBIR, the focus will be on the optimization of the Plasma-shells as a powerful UV light source to stimulate photocatalytic processes, primarily for water treatment. This will have an impact on a large growing global market. The economic delivery of pure water has societal impact, as many in the world still do not have access to clean water. Low cost, rugged, efficient purification systems that will result from this research will help to spread access to clean water. Additional promising applications for the UV light emitting Plasma-shells include sterilization of surface areas, purification of air, medical light therapy, protein analysis, drug discovery, polymer and ink printing, optical sensors and instrumentation, UV ID verification, barcodes, forensic and bodily fluid detection and analysis, counterfeit detection, and superficial/cosmetic treatment.

这个小企业创新研究计划（SBIR）第一阶段项目将允许优化新型等离子体外壳技术，将其整合到大面积紫外线（UV）发射瓦中，用于杀菌应用。等离子体外壳是一种小型气体封装装置，通电后会发光。本研究将著重于改善等离子体外壳密封外壁的透过率，以提高整体效率。等离子体外壳是一种重量轻、成本低、极其坚固的设备。等离子体外壳是唯一的紫外线技术，可以提供超大面积的完全漫射（朗伯）光输出，这是非常有用的传统紫外线杀菌。当在光催化过程中用于激发TiO2时，这些属性将产生更大的影响。紫外线激活的TiO2是一种强大的催化剂，可用于化学物质的分解和污染水中病原体的破坏。然而，TiO2光催化过程的有效结垢依赖于UV光源与TiO2的有效耦合。等离子体壳阵列的大面积低成本朗伯氏输出将提供以前无法获得的照明选择，这将使基于TiO2的水净化系统的高效缩放成为可能。该项目的更广泛影响/商业潜力包括一项新技术，该技术将提供大面积，高效和低成本的紫外线光源。这项研究具有很高的商业潜力，因为最终产品将比目前最先进的UV光源更高效，更环保，更坚固，更具成本效益。在此SBIR下，重点将放在优化等离子体外壳作为强大的UV光源来刺激光催化过程，主要用于水处理。这将对一个庞大的不断增长的全球市场产生影响。纯净水的经济供应具有社会影响，因为世界上许多人仍然无法获得清洁水。这项研究将产生低成本、坚固耐用、高效的净化系统，这将有助于普及清洁水。紫外线发光等离子体外壳的其他有前途的应用包括表面区域的灭菌，空气净化，医疗光疗，蛋白质分析，药物发现，聚合物和油墨印刷，光学传感器和仪器，UV ID验证，条形码，法医和体液检测和分析，伪造检测以及表面/美容治疗。
