The size and surface concentration of Fe NPs significantly decreased with increasing evaporation temperature, which was investigated by transmission electron microscopy (TEM) and x-ray photoelectron spectroscopy. TEM and Raman spectroscopy revealed that the synthesis of SWCNTs with an extremely narrow diameter distribution was achieved and their diameter can be manipulated by evaporation temperature. This diameter-controlled growth of SWCNTs is a step towards SWCNT-based applications.
