Atomically Smooth Nanoporous Alumina Thin Films

Technology Description This technology is a novel method for producing near-atomically smooth, porous alumina thin films by spin coating, in ambient conditions, using aqueous precursors. By utilizing this method, the refractive index of the alumina thin film is tunable from 1.56 to 1.26 by the introduction of a nonionic surfactant in the aqueous precursors....

Synthesis of Solution Precursors From Aluminum and Gallium Bulk Minerals/Materials

The inventors developed novel methods for producing Keggin-like structures containing 13 metal ions ranging from all Gallium to all Aluminum to mixed metals of metal ions including combinations of Gallium, Aluminum, and Indium. These clusters are preorganized with the desired stoichiometry, which makes them ideal synthetic precursors for thin film...
