Laser ablation of a silver plate immersed in virgin coconut oil was carried out for fabrication of silver nanoparticles. A Nd:YAG laser at wavelengths of 1064 nm was used for ablation of the plate at different times. The virgin coconut oil allowed formation of nanoparticles with well-dispersed, uniform particle diameters that were stable for a reasonable length of time. The particle sizes and volume fraction of nanoparticles inside the solutions obtained at 15, 30, 45 min ablation times were 4.84, 5.18, 6.33 nm and 1.0 × 10(-8), 1.6 × 10(-8), 2.4 × 10(-8), respectively. The presented method for preparation of silver nanoparticles in virgin coconut oil is environmentally friendly and may be considered a green method.
将浸泡在初榨椰子油中的银盘进行激光烧蚀，以制备银纳米粒子。使用波长为 1064nm 的 Nd:YAG 激光在不同时间对银盘进行烧蚀。初榨椰子油允许形成具有良好分散性、均匀粒径的纳米粒子，并且在合理的时间内保持稳定。在 15、30 和 45 分钟烧蚀时间下获得的溶液中的纳米粒子的粒径和体积分数分别为 4.84、5.18 和 6.33nm，以及 1.0×10(-8)、1.6×10(-8)和 2.4×10(-8)。在初榨椰子油中制备银纳米粒子的这种方法是环保的，可被视为一种绿色方法。
