Award Description: This Small Business Technology Transfer Phase II project will commercialize laser vapor deposition (LVD?), an innovative technology for depositing thin films and hetero-structures of functional polymers, functionalized nanoparticles and nanoparticle-loaded polymers. LVD 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. During Phase 1, we demonstrated the commercial potential of LVD for depositing nanocomposite materials and con-formal polymer barrier films for OLED applications. This Phase II 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, These will also circumscribe the laser specifications and guide process optimization, leading to lower laser engineering-design and capital costs. 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, one of the scientific frontiers of laser-materials interactions. The outcome of this project will have a significant impact on the reduction to practice of this novel technique for mass production of thin-film organic opto-electronics devices. For example, the OLED is an energy-efficient display and solid-state lighting device. Widespread adoption of solid-state lighting product 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 US Department of Energy. It would also reduce America?s dependence on foreign oil and reduce greenhouse gas emissions, thereby improving the environment. Further-more, 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 every-thing from children?s toys to automobiles, polymers are revolutionizing electronics and opto-electronics 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 ultrashort-pulse laser materials processing applications in the near and mid-infrared.
