- Abstract
This work investigates the synthesis of smart functional coatings (SFC) using chemical solution deposition methods. Chemical solution deposition methods have recently received attention in the materials research community due to several unique advantages that include low temperature processing, high homogeneity of final products, the ability to fabricate materials with controlled surface properties and pore structures, and the ease of dopant incorporation in controlled concentrations. The optical properties of thin films were investigated using UV-Vis spectroscopy, Raman, SEM, and EDS, with the aim of developing a protective transparent coating for a ceramic surface as a first line of defense for tamper indication. The signature produced by the addition of rare earth dopants will be employed as an additional tamper indicating feature. The integration of SFCs as part of a broader verification system such as an electronic seals can provide additional functionality and defense in depth. SFCs can improve the timeliness of detection by providing a robust, in-situ verifiable tamper indication framework.
