A reverse microemulsion approach has been explored for the synthesis of layered gadolinium hydroxide (LGdH) nanoparticles in this work. This method uses oleylamine as a multifunctional agent, acting as surfactant, oil phase and base. 1-butanol is additionally used as a co-surfactant. A systematic study of the key reaction parameters was undertaken, including the volume ratio of surfactant (oleylamine) to water, the reaction time, synthesis temperature, and the amount of co-surfactant (1-butanol) added. It proved possible to obtain pristine LGdH materials at temperatures of 120 °C or below with an oleylamine: water ratio of 1:4. Using larger amounts of surfactant or higher temperatures caused the formation of Gd(OH)₃, either as the sole product or as a major impurity phase. The LGdH particles produced have sizes of ca. 200 nm, with this size being largely independent of temperature or reaction time. Adjusting the amount of 1-butanol co-surfactant added permits the size to be varied between 200 and 300 nm.

在这项工作中，已经探索了一种反向微乳液方法，用于合成层状氢氧化hydroxide（LGdH）纳米颗粒。该方法使用油胺作为多功能剂，起表面活性剂，油相和碱的作用。1-丁醇还用作助表面活性剂。对关键反应参数进行了系统研究，包括表面活性剂（油胺）与水的体积比，反应时间，合成温度和助表面活性剂（1-丁醇）的添加量。事实证明，在120  °C或更低的温度下，油胺：水的比例为1：4可获得原始LGdH材料。使用大量的表面活性剂或较高的温度导致形成Gd（OH）₃，作为单一产品或主要杂质相。产生的LGdH颗粒的尺寸约为 200  nm，该尺寸在很大程度上与温度或反应时间无关。调节1-丁醇助表面活性剂的添加量可以使尺寸在200至300  nm之间变化。
