| Abstract | Recently, a significant amount of studies have been carried out on sol-gel films for optical applications, mostly motivated by the quickness and low cost of the film preparation process. Overcoating films of different density and thickness can produce waveguides for visible light as well as for X-rays. In order to preserve the coherence properties of the guided light, improvements in the current quality of the films are necessary as well as an appropriated technique for structural characterization and quality control. X-ray specular reflectivity can be such a technique, but it is limited by the complexity of the internal nanostrutucture of the films. In this work, we have developed a procedure to fit the specular reflectivity and extract the exact density profile of sol-gel films. It is applied to analyze a single compound film produced from a sol-gel of Er2O3 nanoparticles. It correlates the density variations and roughness with the steps of the preparation process. Moreover, we have also characterized an X-ray waveguide of Er2O3/TiO2/Er2O3 and theoretically optimized its structure to demonstrate the effects of density floating and roughness on the waveguidance efficiency. |
