采用一种简单的复合氢氧化物介导合成方法制备了超长、单晶、六方结构的La（OH）（3）纳米带。单一La（OH）（3）纳米带的可检测导电行为预示着它们在传感器中的潜在应用。La（OH）（3）纳米带经煅烧后得到La2O3纳米带。这两种类型的纳米带在紫外线激发下都发出紫光荧光，可用于生物标记。
A facile composite-hydroxide-mediated synthesis method is adopted to prepare ultralong, single-crystalline, hexagonal structured La(OH)(3) nanobelts. The detectable conductive behavior of a single La(OH)(3) nanobelt promises their potential application in sensors. La2O3 nanobelts can be obtained by calcination of the La(OH)(3) nanobelts. Both types of nanobelts fluoresce with purple light under UV excitation, which may be used in biological labeling.
