    　View Summary

    Perylene microcrystals in aqueous solutions containing various concentration of Triton X-100, nonionic surfactant, were irradiated by a nanosecond laser under various irradiation conditions including the fluence and length of irradiation time. Perylene nanoparticles with diameters of several hundred nm were formed by the laser irradiation only when Triton X-100 was added in the solutions at sufficiently high concentrations of the surfactant. The transfer of perylene molecules into the micelles of Triton X-100 was avoided by optimizing the concentrations of the surfactant so that only perylene nanoparticles were obtained in the aqueous solutions.
