气溶胶技术被用于合成用于等离子体材料的球形且单分散的银纳米粒子。这些粒子是通过蒸发 - 冷凝技术产生的，随后分别使用差分迁移率分析仪和管式炉进行尺寸筛选和烧结。最后，用静电沉淀器将纳米粒子收集在玻璃基底上。使用扫描迁移率粒子分析仪测量粒子尺寸分布，并使用透射电子显微镜进行验证。使用分光光度计测量所制备样品的消光光谱，这些样品包含直径约为50、90和130纳米的粒子。通过控制粒子尺寸，局域表面等离子体共振的偶极峰在398至448纳米的波长之间进行了调谐。此外，正如用于表征测量光谱的简化理论模型所预测的那样，在更短的波长处观察到了四极共振。
Aerosol techniques were used to synthesize spherical and monodisperse silver nanoparticles for plasmonic materials. The particles were generated with an evaporation–condensation technique followed by size selection and sintering with a differential mobility analyzer and a tube furnace, respectively. Finally, the nanoparticles were collected on a glass substrate with an electrostatic precipitator. The particle size distributions were measured with a scanning mobility particle sizer and verified with a transmission electron microscope. A spectrophotometer was used to measure the optical extinction spectra of the prepared samples, which contained particles with diameters of approximately 50, 90 and 130 nm. By controlling the particle size, the dipolar peak of the localized surface plasmon resonance was tuned between wavelengths of 398 and 448 nm. In addition, quadrupolar resonances were observed at shorter wavelengths as predicted by the simplified theoretical model used to characterize the measured spectra.
