Influence of the solution volume on the growth of C60 nanowhiskers

C60 nanowhiskers (C60NWs) were synthesized by a modified LLIP method with manual mixing.The size of C60NWs asymptotically approaches the upper limit when increasing the solution volume.The number density of C60NWs and the solution volume show a linear double logarithmic relation.

The lengths and diameters of C60 nanowhiskers (C60NWs) grown in solutions were investigated relative to the inner diameter of the glass bottle and the solution volume while maintaining the volumetric ratio of C60-saturated toluene and isopropyl alcohol at 1:1. The mean lengths and diameters of the C60NWs increased, and the distribution of the lengths and diameters broadened when increasing the solution volume. The mean crystal nucleus size of the C60NWs was determined by analyzing the size dependence of C60NWs on the solution volume. The lengths and diameters of C60NWs asymptotically approach their upper limits when increasing the solution volume.
