Abstract
We present an observation of depolarized scattering by silver colloids. The profile of the wavelength-dependent anisotropy of the colloidal solution of silver nanoparticles traces the plasmonic extinction spectrum. The scattering component of the colloid extinction spectrum is responsible for the depolarization effect. We believe that the presence of the orthogonal component in the silver colloid scattering can be used in dye-less sensing devices.
摘要
我们展示了银胶体的去极化散射观测结果。银纳米颗粒胶体溶液的波长依赖性各向异性曲线追踪了等离子体消光光谱。胶体消光光谱的散射成分导致了去极化效应。我们认为银胶体散射中正交分量的存在可用于无染料传感装置。
