La(OH)(3) nanorods were self-stacked on the glass slide substrates using an aqueous suspension obtained from the hydrolysis of LaOCl. The key for producing a high optical quality film of La(OH)(3) lies in the preparation of an aqueous suspension in which La(OH)(3) nanorods are well dispersed. These thin-film coatings of La(OH)(3) nanorods led to a significantly reduced reflective losses in the visible region, exhibiting an attractive and potentially useful single-layer antireflection property. Furthermore, La(OH)(3) nanorod layer provides a sufficiently porous and rough surface required to achieve superhydrophilicity. Thus, when SiO(2) nanoparticles of ca. 20nm in diameter were deposited onto La(OH)(3) layer of high roughness, the resulting La(OH)(3)/SiO(2) film demonstrated an interesting nanoporosity-derived superhydrophilicity and antifogging property with no significant loss of antireflective property.
La(OH)(3)纳米棒通过自组装的方式堆积在玻璃载玻片上，使用的是 LaOCl 水解得到的水性悬浮液。制备具有高光学质量的 La(OH)(3)薄膜的关键在于制备 La(OH)(3)纳米棒能够很好分散的水性悬浮液。这些 La(OH)(3)纳米棒的薄膜涂层显著降低了可见光区域的反射损耗，表现出吸引人的、具有潜在应用价值的单层抗反射性能。此外，La(OH)(3)纳米棒层提供了足够多孔和粗糙的表面，以实现超亲水性。因此，当直径约为 20nm 的 SiO(2)纳米颗粒沉积在高粗糙度的 La(OH)(3)层上时，所得到的 La(OH)(3)/SiO(2)薄膜表现出有趣的纳米多孔衍生的超亲水性和防雾性能，同时没有明显的抗反射性能损失。
