Fifth generation ethylendiamine-core poly(amidoamine) (PAMAM G5) is presented as an efficient capping agent for the preparation of metal and semiconductor nanoparticles by ps laser ablation in water. In particular, we describe results obtained with the fundamental, second and third harmonic of a ps Nd:YAG laser and the influence of laser wavelength and pulse energy on gold particle production and subsequent photofragmentation. In this framework, the role of the dendrimer and, in particular, its interactions with gold clusters and cations are accounted.
第五代乙二胺核聚（酰胺胺）（PAMAM G5）被提出作为一种高效的封端剂，用于通过皮秒激光在水中烧蚀制备金属和半导体纳米颗粒。特别是，我们描述了用皮秒Nd:YAG激光的基频、二次谐波和三次谐波获得的结果，以及激光波长和脉冲能量对金颗粒生成和随后光碎片化的影响。在此框架下，考虑了树枝状大分子的作用，特别是其与金簇和阳离子的相互作用。
