So, the volumes of NRL used for samples L1 and L2 seem to be insufficient to reduce and passivate all the Ag(I) ions. In other words, more silver nanoparticles were produced when more NRL was added. This can be explained by reaction stoichiometry or by kinetic reasons when the increase of NRL con opposite trend. As the AgNO3 concentration was diminished, the size distribution became broader. This could be explained if we admit that the average diameter obtained from DLS comes not only from “naked” silver nanoparticles, but from nanoparticles surrounded by NRL. At lower silver nitrate concentration the NRL:Ag(I) ratio is higher, thus more NRL molecules can be attached to the surface of the particles. The NRL molecules may form more than a monolayer onto the nanoparticles. This film can absorb water, giving rise to tumescence of the composite nanoparticles and, consequently, the size of the particles becomes larger.
