This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Small Business Technology Transfer Research (STTR) Phase II project seeks to commercialize an innovative technology for depositing thin films and heterostructures of functional polymers, functionalized nanoparticles and nanoparticle-loaded polymers. Laser vapor deposition (LVD - trademarked) can be used to increase efficiency and reduce cost of thin-film devices as varied as organic light emitting diodes (OLEDs), organic solar cells and polymer chemosensors. This project will prove that LVD can meet industrial production requirements by (a) performing scaling studies of the process-throughout versus laser power in various process configurations and (b) building a table-top mid-infrared laser prototype using nonlinear optical frequency conversion from a commercially available high-power near-infrared laser. This objective will be supported by thorough studies on the physical mechanism of laser-materials interaction under mid-infrared vibrational excitation. The outcome of this project will also provide the development roadmap for high power industrial lasers for materials processing applications in mid-infrared wavelength spectrum.The broader impact/commercial potential from this technology will be the technique for mass production of thin-film organic optoelectronics devices. For example, the OLED is an energy-efficient display and solid-state lighting device. Widespread adoption of solid-state lighting products such as white-light OLEDs could cut the US consumption of electricity for lighting by 29%, while saving the nation's households about $125 billion in the process, according to the Department of Energy. It would also reduce America's dependence on foreign oil and reduce greenhouse gas emissions, thereby improving the environment. Furthermore, LVD will accelerate the penetration of organic electronics into the consumer space and create new applications such as flexible displays. Just as polymers have replaced metal in everything from children's toys to automobiles, polymers are revolutionizing electronics and optoelectronics by reducing costs and opening new markets for devices such as polymer electronics and nanostructured displays. In addition, the blueprint of table-top high-power lasers developed in this process will provide a new path into ultra-short-pulse laser materials processing applications in the near and mid-infrared.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该小企业技术转让研究（STTR）第二阶段项目旨在将用于沉积功能聚合物，功能化纳米颗粒和纳米颗粒负载聚合物的薄膜和异质结构的创新技术商业化。激光气相沉积（LVD -注册商标）可用于提高效率并降低薄膜器件的成本，如有机发光二极管（OLED）、有机太阳能电池和聚合物化学传感器。该项目将通过以下方式证明LVD可以满足工业生产要求：（a）对各种工艺配置中的工艺吞吐量与激光功率进行缩放研究，以及（B）使用非线性光学频率构建台式中红外激光器原型来自市售高功率近红外激光器的转换。深入研究中红外振动激发下激光与物质相互作用的物理机制将为这一目标提供支持。该项目的成果还将为中红外波段材料加工应用的高功率工业激光器提供发展路线图。该技术的更广泛影响/商业潜力将是大规模生产薄膜有机光电子器件的技术。例如，OLED是节能显示器和固态照明设备。据美国能源部称，广泛采用白光OLED等固态照明产品可以将美国照明用电量减少29%，同时为美国家庭节省约1250亿美元。它还将减少美国对外国石油的依赖，减少温室气体排放，从而改善环境。此外，LVD将加速有机电子产品向消费领域的渗透，并创造新的应用，如柔性显示器。正如聚合物已经取代了从儿童玩具到汽车的所有金属一样，聚合物正在通过降低成本和为聚合物电子和纳米结构显示器等设备开辟新市场来彻底改变电子和光电技术。此外，在此过程中开发的台式高功率激光器的蓝图将为近红外和中红外超短脉冲激光材料加工应用提供新的途径。
