| Research Abstract |
Laser ablation experiments toward the silver plate immersed in toluene, which were solvented with supercritical CO2, were performed. It was found that silver nanoparticles were formed by the laser ablation processes and it was also confirmed that silver nanoparticles were covered with carbon film. To investigate further the origin of the carbon film formed by the laser ablation into toluene, GC-MS analysis were carried out to the liquid after the laser irradiation. Pyrene was observed as one of the major products. And thus it was concluded that pyrene formed by the laser pyrolysis of toluene was the origin of the carbon film. It was also found that pyrene was also formed using the other solvents after the laser irradiation to those solvents. Laser ablation of Cu plate under the supercritical CO2 condition was also performed and the graphene formation was convinced by the Raman signal analysis of the deposited film on Cu plate.
