摘要

在这项工作中,我们提出了一种在柔性玻璃上制造大面积纳米颗粒阵列的新策略。纳米球光刻(NSL)与热降解相结合,可以生产有序的金(Au)/钴(Co)纳米粒子阵列。聚苯乙烯(PS)珠组装在柳树®玻璃形成一个六边形填充单层。接下来,通过电子束蒸发将Au和Co共沉积到PS珠上。在高温下(600℃)降解PS珠模板,得到平均粒径为118±11 nm的有序Au-Co阵列。用带积分球的分光光度计测量了总积分透射率、Tint和前向散射系数Sf。在~660 nm处分别有最小峰和最大峰。

Fabrication of Ordered Au–Co Nanoparticle Arrays
In this work, we present a novel fabrication strategy for large-area nanoparticle (NP) arrays on flexible glass. Nanosphere lithography (NSL) is used in combination with thermal degradation to produce ordered arrays of gold (Au)/cobalt (Co) NPs. Polystyrene (PS) beads were assembled on Willow® glass to form a hexogonally-packed monolayer. Next, Au and Co were applied onto the PS beads using co-deposition via e-beam evaporation. The PS bead template was degraded under high temperature (600° C), leaving behind an ordered Au–Co array with average particle diameter of 118±11 nm. The total integrated transmission, Tint, and forward scattering, Sf, were measured using a spectrophotometer with an integrating sphere. Both measurements revealed a minimum and maximum peak at ~660 nm, respectively.
