A single‐step process made it possible to obtain films consisting of silver nanoparticles dispersed in a nanostructured titania matrix, as presented by Daniela Manno, Antonio Serra, and co‐workers in article number 2000124 . The plasmon resonance peak, red‐shifted with respect to silver nano‐colloidal solution, represents the peculiar feature of the obtained films. Morphological (SEM, TEM, HREM), structural (SAD, XRD), and spectroscopic (Raman spectroscopy) characterization, supported by Monte Carlo simulation processes, attest that the Ag nanoparticles are spherical, and homogeneously distributed in the TiO 2 dielectric matrix in the anatase structural modification.
