Instrumentation to Support the Research Program of Multi-Beam Pulsed Laser Deposition of Polymer-Inorganic Nanocomposite Films
Abstract
Dr. A. Darwish, PI at Dillard University, New Orleans is currently conducting research projects ÒLaser deposition of polymer nanocomposite filmsÓ and ÒMulti-beam pulsed laser deposition of inorganic-polymer nanocomposite thermo-electric films for energy harvestingÓ sponsored by AFOSR through research Grants FA 9550-12-1-0068, and W911NF-15-1-0446 . The first, five year project is entering its fourth year. The second project is in its first year. The main common objective of the projects is to investigate feasibility of the new method of pulsed laser deposition (PLD) invented by Dr. Darwish, which is called multiple-beam pulsed laser deposition (MBPLD). It is expected that the method will be especially beneficial for making polymer/inorganic nanocomposite films, which conventional PLD methods fail to produce. It has been already demonstrated for the first time that the proposed new MBPLD in its variation called multi- beam matrix assisted pulsed laser evaporation (MB-MAPLE) made possible to transfer the highly efficient inorganic upconversion rare earth (RE) fluoride phosphors in nanocomposite polymer films preserving the RE compound crystalline structure and high-brilliance upconversion emission. This is due to much better control of the deposition process of the materials of different nature. Also, the MB-MAPLE method has been successfully exploited to produce unique inorganic/polymer nanocomposite films made of semiconductor aluminum doped zinc oxide (AZO) doped with nanoparticles and nanofibers of carbonized polymer poly(methyl methacrylate) known as PMMA with improved thermo-electric properties.
