Outline of Final Research Achievements

Laser ablation of a metal block target held in a solvent generates plasma vapor, and the vaporized metal atoms react with the surrounding solvent molecules, condensing rapidly to produce particles. Metastable particles are produced by the rapid quenching of highly excited states, and the metastable phase may stabilize as a result of the large surface effects of the nanoparticles. Laser ablation of an iron metal in organic solvents were performed to produce metastable iron carbide nanoparticles that were hardly obtainable using conventional methods. Laser ablation in liquid is typically performed in a stagnant solvent. However, if the particles remain suspended in the solvent after production, they can deteriorate because of the effects of prolonged laser irradiation. In order to investigate the formation mechanism, we carried out laser ablation in liquids using a cell with a circulating solvent to obtain particles produced solely by laser ablation.

Academic Significance and Societal Importance of the Research Achievements

ナノサイズの微粒子は通常の大きな固体とは異なった性質を持つことが知られている。溶液中で金属試料を強いレーザー光で照射すると金属プラズマが生成し、周囲の溶媒分子によって急激に冷却されたり、溶媒分子と化学反応を起こしたりするため、容易に金属ナノ粒子を生成することができる。このような手法によって炭化鉄のナノ粒子を合成した。炭化鉄は触媒として重要であることが知られているが、磁性材料としても有用である。本研究によって通常の合成法では得ることができない組成を持った炭化鉄ナノ微粒子をえることに成功した。また、液相レーザーアブレーションによってナノ粒子が生成する過程での反応機構に関する知見が得られた。
