摘要：
本文给出了激光烧蚀锌在阴离子表面活性剂十二烷基硫酸钠（SDS）、琥珀酸二辛酯磺酸钠（AOT）水溶液中形成的胶体溶液的光学特性、分散相的组成和形态的实验研究数据。结果表明，通过研究胶体的光吸收光谱，X射线光谱和AFM图像提取的胶体固相，它是可能的跟踪动力学的ZnO纳米结构形成从几个纳米尺寸的锌纳米碎屑ZnO分形聚集体（FA）的大小高达数百纳米。该过程的决定因素是平均功率和烧蚀暴露、激光脉冲的频率、胶体老化时间、溶液中表面活性剂的类型和浓度。在选择适当的制度下，与氧化锌一起得到了其它纳米产物-氢氧化锌和有机-无机层状复合物\ce{[(β) - Zn(OH)2 + SDS]}。
英文摘要：
The data of experimental studies of optical characteristics of colloidal solutions, composition and morphology of its dispersed phase, resulting from laser ablation of zinc in aqueous solutions of anionic surfactants --- sodium dodecyl sulfate (SDS), dioctyl sodium sulfosuccinate (AOT) are presented. It is shown that by studying the optical absorption spectra of the colloid, X-ray spectra and AFM-images of extracted from colloid solid phase, it is possible to trace the dynamics of ZnO nanostructures formation from zinc nanoclasters size of several nanometers to ZnO fractal aggregates (FA) size up to hundreds of nanometers. Determinants of this process are the average power and an ablation exposure, the frequency of the laser pulses, the colloid aging time, the type and concentration of surfactant in solution. In the selection of appropriate regimes, along with zinc oxide obtained other nanoproducts --- hydrozincit and organo-inorganic layered composite \ce{[(β) - Zn(OH)2 + SDS]}.
