Embodiment

[0059]In an embodiment, the first nanostructure on the substrate is carboxylated polystyrene nano-beads (purchased from Thermo Fisher Scientific (Thermo Fisher Scientific), product number W050CA), and the particles of carboxylated polystyrene nano-beads The diameter is 530 nm. Next, an oxygen plasma etching process is performed on the substrate with the first nanostructure, and the etching time is 120 seconds. Next, a gold plating process is performed to form metal layers with different thicknesses on the first nanostructures of the substrate. Then, the Raman scattering intensity of 2mM rhodamine 6G was measured for the substrates with different thickness metal layers, and the main scattering peak of rhodamine 6G was 1360cm -1 .

The metal structure is located on the surfaces of the plurality of second nanostructures. The invention also provides a preparation method of the optical substrate.

Description

technical field [0001] The present invention relates to a substrate and a preparation method thereof, and in particular relates to an optical substrate and a preparation method thereof. Background technique [0002] Biomedical optoelectronics is a new field combining optoelectronic technology and biomedicine. It can not only be applied to early disease detection, but also can achieve the effect of disease treatment through light guidance or light excitation. [0003] Biomedical optoelectronics is used in disease detection. In order to achieve the purpose of surface enhanced Raman scattering (SERS), the current technology can use nanotechnology to increase the surface roughness of the substrate. However, in order to improve the surface roughness of the substrate, the existing manufacturing process is cumbersome and complicated. Therefore, how to simplify the nanotechnology manufacturing process and at the same time make the optical substrate meet the requirements of the curre...
