Abstract
The development of large-area, Na-β″-Al2O3 single-crystal films on sapphire substrates via vapor reaction is reported. The films form at the expense of the sapphire which reacts with the alkali-vapors generated from mixed (Na,Li)-β″-Al2O3 powders occupying the same space as the sapphire. A number of β″-Al2O3 single-crystal, large area isomorphs have been synthesized via ion exchange and their refraction and luminescence properties are reported. Patterned luminescence has been achieved in Cu+-doped single-crystal films using an electrochemical cell with + electrolyte separator between aqueous-solution electrodes. Ag+ ions are injected into the β″-Al2O3 electrolyte and Na+ expelled. The distribution of luminescent and environment ions is controlled by electrical charge and the chemical potential of the ions in the solution electrodes.
