Tīmeklis2024. gada 9. nov. · Noble-metal-free surface-enhanced Raman scattering (SERS) substrates have attracted great attention for their abundant sources, good signal uniformity, superior biocompatibility, and high chemical stability. TīmeklisRaman amplification is based on a stimulated Raman scattering process involving pump and signal photons on the one hand, and optical phonons of the glass material on the other hand. This is a nonlinear effect and so is polarization dependent and requires high power densities. This inelastic process converts one pump photon into a signal …

Tīmeklis拉曼光谱是一种 散射光谱 ，它是基于光和材料的相互作用而产生的。 拉曼散射的定义：激光光源的高强度入射光被分子散射时，大多数散射光与入射激光具有相同的波长（颜色），这种散射称为瑞利散射。 然而， 还有极小一部分（大约1/10^9）散射光的波长（颜色）与入射光不同，其波长的改变由测试样品（所谓散射物质）的化学结构所决 …
TīmeklisRaman spectroscopy ( / ˈrɑːmən /) (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. [1] Raman spectroscopy is commonly used in chemistry to provide a structural … TīmeklisRealizing Raman enhancement on a flat surface has become increasingly attractive after the discovery of graphene-enhanced Raman scattering (GERS). Two-dimensional (2D) layered materials, exhibiting a flat surface without dangling bonds, were thought to be strong candidates for both fundamental studies of this Raman enhancement …
