采用LB法在硅衬底上制备了高度有序的硫醇包裹金纳米粒子单层膜。研究了包封金颗粒LB铺展悬浮液中颗粒浓度和溶剂类型对颗粒有序度的影响。我们发现，在氯仿中0.06-0.3 mg/mL的低颗粒浓度对于高质量金颗粒单层的制造是最佳的。由于所提出的方法不限于金颗粒，因此认为这是一种用于制造各种颗粒尺寸和组成的量子点结构的实用方法。(C)2001年美国真空学会。
A highly ordered monolayer film of alkanethiol-encapsulated gold nanoparticles was fabricated on a silicon substrate by using the Langmuir- Blodgett (LB) method. The effects on the particle order, of the particle concentration and the type of solvent of the LB spreading suspension of encapsulated gold particles, were studied. We found that a low particle concentration of 0.06-0.3 mg/mL in chloroform is optimal for the fabrication of high quality gold particle monolayers. Since the proposed method is not restricted to gold particles, it is believed to be a practical process for fabricating quantum dot structures of various particle sizes and compositions.
