| Zeolites prepared as thin films or membranes have potential applications as size-selective sensors for small molecules, electrode coatings, and as low-k dielectric materials. Our aim is to study the electrical and electro-optic properties of alkali metal doped silica zeolites, M@SZ, also known as inorganic electrides. As bulk powders, M@SZ are prepared by the gas phase addition of Na-Cs to a silica zeolite. One of the defining characteristics of M@SZ is a broad NIR band suggestive of electron delocalization. To grow thin (0.1-2.0 micron) MFI films, quartz, ITO, or suitably modified gold substrates are placed into hydrothermal synthesis solutions. The result is a MFI film that grows preferentially with the b-axis normal to the substrate surface. Once the SDA has been removed, doping with alkali metal under inert atmosphere yields the thin film inorganic electride. The properties of Cs@MFI prepared as thin films and bulk powders will be discussed. |
