Problems solved by technology
[0004] The existing surface-enhanced Raman scattering effect needs to be irradiated with an external light source, and the surface-enhanced Raman scattering (SERS) effect occurs on a specific metal structure. Each time it is used, the light source must be connected to the structure where the surface-enhanced Raman scattering effect occurs. Waveguide coupling will waste time, and each operation will have subtle differences, which will easily affect the accuracy

Abstract
The invention relates to an electrically-driven surface Raman enhanced light source, and the light source comprises a substrate layer. A metal layer is arranged above the substrate layer, and a quantum well layer is arranged above the metal layer. A metal mesh layer is arranged above the quantum well layer, and a metal nanorod is arranged on the metal mesh layer. The electrically-driven surface Raman enhanced light source enables a surface enhanced Raman scattering effect light source to be combined with a structure generating a surface enhanced Raman scattering effect, so when the surface enhanced Raman scattering effect research is carried out, the light source does not need to be coupled, and light waves generated by the light source can be directly propagated in the surface-enhanced Raman scattering effect structure; energy loss is small, time is saved, fine difference caused by frequent coupling is avoided, and the surface-enhanced Raman scattering effect research precision can beimproved.
Description
technical field [0001] The invention belongs to the technical field of surface Raman light sources, and in particular relates to an electrically driven surface Raman enhanced light source. Background technique [0002] Surface-Enhanced Raman Scattering (SERS for short), using the usual Raman spectroscopy to measure samples adsorbed on the surface of colloidal metal particles such as silver, gold or copper, or adsorbed on the rough surface of these metal sheets sample. [0003] The surface-enhanced Raman scattering (SERS) effect refers to that in some specially prepared metal good conductor surfaces or sols, in the excitation region, due to the enhancement of the electromagnetic field on the surface or near the surface of the sample, the Raman scattering signal of the adsorbed molecules is larger than that of the ordinary Raman scattering signal. Mann scattering (NRS) signal greatly enhanced phenomenon. Surface-enhanced Raman overcomes the shortcomings of low sensitivity of...
