A range of carbon nanoparticles together with polyyne chains are formed when liquid benzene is irradiated with 120fs pulses of intensity≈1×10 14 Wcm −2 . The morphology and composition of these nanoparticles are reported. Atomic force microscopy (AFM) shows irradiation result in the formation of spherical, ellipsoidal and toroidal nanoparticles with sizes between 1 and 50nm. Surface...
The production of polyyne molecules arising from the irradiation of liquid octane with femtosecond (fs) laser pulses has been studied using time of flight mass spectrometry (TOFMS). We attribute the primary formation mechanism for polyynes in solution to the creation of small polyyne and cumulene molecules formed in molecular dissociative ionization, that subsequently increase in length through addition...
