A study of iron nanocluster synthesis and oxidation reaction by using a flash camera

Iron nanoclusters and nanoparticles were grown from iron carbonyl (Fe(CO)5) by using thermal decomposition. The recrystallization structure of the iron nanocluster was controlled by varying the temperature of the thermal decomposition. A permanent magnet was used to increase the efficiency of iron nanocluster growth. Recrystallized iron nanoclusters were confirmed to have various shapes depending on the temperature of the thermal decomposition. Nanoclusters of a wire type were grown at 600 ^◦C. The nanocluster wire confirmed the occurrence of a photoreaction caused by exposure to a flashing light source.
