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.

在Triton X-100水溶液中通过激光烧蚀per微晶形成纳米颗粒

在纳秒级激光下，在各种辐照条件下，包括通量和辐照时间长短，对含有各种浓度的Triton X-100（非离子表面活性剂）的水溶液中的微晶进行辐照。仅当将Triton X-100以足够高浓度的表面活性剂添加到溶液中时，才通过激光辐照形成直径为几百纳米的纳米颗粒。通过优化表面活性剂的浓度可以避免per分子转移到Triton X-100胶束中，从而在水溶液中仅获得per纳米颗粒。
