我们报道了以聚苯乙烯介观微球为模板合成银纳米盘。TEM测量表明，平均圆盘厚度为9.0 ± 1.0 nm，直径为36 ± 8 nm。这些粒子显示出强烈的电子光谱，与球体（紫色与黄色溶液）明显不同。我们目前的电磁理论计算表现出与所观察到的光谱的定性匹配，使我们能够分配几个等离子体共振功能。
We report the synthesis of Ag nanodisk using polystyrene mesospheres as templates. TEM measurements show that the average disk thickness is 9.0 ± 1.0 nm and the diameter is 36 ± 8 nm. The particles exhibit an intense electronic spectrum that differs markedly from that for spheres (purple vs yellow solutions). We present electromagnetic theory calculations which exhibit a qualitative match with the observed spectrum, enabling us to assign several of the plasmon resonance features.
