Grazing incidence small angle X-ray scattering (GISAXS) was used to study the structure and interparticle spacing of monolayers of organic ligand-stabilized iron oxide nanocrystals floating at the air-water interface on a Langmuir trough, and after transfer to a solid support via the Langmuir-Blodgett technique. GISAXS measurements of the nanocrystal arrangement at the air-water interface showed that lateral compression decreased the interparticle spacing of continuous films. GISAXS also revealed that Langmuir-Blodgett transfer of the nanocrystal layers to a silicon substrate led to a stretching of the film, with a significant increase in interparticle spacing.
掠入射小角X射线散射（GISAXS）被用于研究在Langmuir槽中气-水界面上漂浮的有机配体稳定的氧化铁纳米晶体单层的结构和颗粒间间距，以及通过Langmuir-Blodgett技术转移到固体支撑物上之后的情况。在气-水界面处对纳米晶体排列进行的GISAXS测量表明，横向压缩减小了连续膜的颗粒间间距。GISAXS还表明，纳米晶体层向硅衬底的Langmuir-Blodgett转移导致膜的拉伸，颗粒间间距显著增加。
