The present invention provides photoluminescent iron-doped barium stannate materials absorbing ultraviolet (UV) light and exhibiting strong near-infrared (NIR) luminescence. Such materials exhibit increased integrated photoluminescence intensity in comparison to known BaSnOand iron-doped barium stannate materials, and therefore they are particularly useful for the production of photoluminescent security ink compositions and transparent covert security features with improved anti-counterfeiting resistance that can be used for protection of documents and articles against counterfeit and illegal reproduction.

The invention relates to thin film single layers, electronic components such as multilayer capacitors which utilize thin film layers, and to their methods of manufacture. Chemical solution deposition and microcontact printing of dielectric and electrode layers are disclosed. High permittivity BaTiO3 multilayer thin film capacitors are prepared on Ni foil substrates by microcontact printing and by chemical solution deposition. Multilayer capacitors with BaTiO3 dielectric layers and LaNiO3 internal electrodes are prepared, enabling dielectric layer thicknesses of 1 &#x3bc;&#x3bc;m or less. Microcontact printing of precursor solutions of the dielectric and electrode layers is used.
