Formation of shell-shaped carbon nanoparticles above a critical laser power in irradiated acetylene
A one-step synthesis of onion-like, shell-shaped carbon nanoparticles (SCNPs) is reported. Exposure of an acetylene flow to a continuous-wave infrared CO2 laser produces SCNPs with continuous bent-graphene layers in bulk quantity, but only above a threshold laser power.
