Substrate for surface-enhanced Raman spectroscopy and method for producing same

摘要

Disclosed are a substrate for surface-enhanced Raman spectroscopy allowing surface-enhanced Raman signals to be notably improved, even in cases of long-term storage, by producing the substrate so that metal nanoparticles thereon are distanced several nanometers apart, and a method for producing the substrate for surface-enhanced Raman spectroscopy at a large scale with simple equipment and at a low production cost.

主权项

1. A substrate for surface-enhanced Raman spectroscopy comprising:
a polymer substrate of which protuberant structures having an upper protruded curved surface are formed to be spaced-apart on a first surface; metal-containing nanoparticles formed on the protuberant structures; and a metal-containing thin layer formed on a part or the entire part of the first surface of the polymer substrate where the protuberant structures are not formed, wherein the metal-containing nanoparticles and the metal-containing thin layer are formed by a vapor deposition with a metal-containing Raman active material on the first surface at the same time, and wherein the metal-containing Raman active material is first deposited uniformly on the first surface and on the protuberant structures but intensively on the protuberant structures as the deposition is progressed.
