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
