| Resumen : | Nanoparticles with optical and magnetic responses are of great applicability in different fields. In this
work, zero valent iron nanoparticles were prepared by laser ablation and stabilized in a surfactant solution
to keep particles dispersed and protected in the solution. Optical and magnetic properties of nanoparticles
were measured, by UV and Mössbauer spectroscopy. The results show the formation of
nanoparticles of a-Fe (ferromagnetic). Our method of preparation, which uses a high H+ concentration
in the medium, diminishes the zero valent iron oxidation, producing iron nanoparticle with a core of
a-Fe and a small shell probably composed of iron oxides |
