“…In fact, the LB technique allows deposition of films with molecular resolution thus providing the inclusion of exactly the required quantity of metal ions, which finally determines the amount of particles precipitated inside the organic matrix. Most of the works deal with the fatty acid salt LB films as precursors, − but there is, however, the possibility of particle formation in various LB precursors. − To produce nanoparticles, the samples with the deposited LB films are placed into a H 2 S atmosphere. Such a treatment results in the protonation of fatty acid headgroups and in the formation of metal sulfide in the form of particles with nanometer dimensions.…”
