Controlled deposition of silver nanoparticles in mesoporous single- Or multilayer thin films: From tuned pore filling to selective spatial location of nanometric objects
Silver nanoparticle assemblies are embedded within mesoporous oxide thin films by an in situ mild reduction leading to nanoparticle-mesoporous oxide thin-film composites (NP@MOTF). A quantitative method based on X-ray reflectivity is developed and validated with energy dispersive spectroscopy in ord...
