Abstract Laser ablation of Co, CoO and Co 3 O 4 was carried out in water and hexane. Nano-sized particles were produced from all materials in both solvents. It was found that atomic compositions of nanoparticles depended on solvent species in which laser ablation was carried out. In water, Co 3 O 4 nanoparticles were produced from all materials. In hexane, Co nanoparticles were produced from Co 3 O 4 and Co, while CoO particles were dominantly produced from CoO.
