Abstract
The present invention discloses an SERS substrate of a metal-modified semiconductor-based bionic compound eye bowl structure and a construction method, and belongs to the technical field of nano materials. The present invention is based on a multi-time interface self-assembly method. Firstly, a small ball template is constructed by using a gas-liquid interface assembly process. Then, a semiconductor bowl structure array is induced to be formed by the template by using a solid-liquid interface assembly process. Next, a semiconductor bowl is assembled to a surface of a pyramid-shaped cone to form a bionic compound eye structure by using a transfer process. Finally, a surface of the bionic compound eye structure is modified with a layer of uniformly distributed metal particles by a physical deposition method or a chemical deposition method, thereby forming the SERS substrate of the metal-modified semiconductor-based bionic compound eye bowl structure.
