Abstract
A double frame nanoparticle synthesis method includes: forming a first platinum layer of a closed loop structure on an edge region of a 2-dimensional gold nanoparticle; removing a portion of the gold nanoparticle in an exposed inner region thereof free of the first platinum layer, thereby forming a single frame structure; growing a first gold thin film on the single frame structure; forming a second platinum layer on inner and outer edge regions of the first gold thin film; removing a portion of the first gold thin film in an exposed region thereof free of the second platinum layer, thereby forming a double frame structure having an inner frame of a closed loop structure, and an outer frame having a closed loop structure surrounding the inner frame and partially connected to the inner frame; and forming a second gold thin film on a surface of the double frame structure.
