(a) Extinction spectra of the triangle–rod dimer nanostructure with varying the center offset g for the fixed gap distance d = 2 nm; (b) extinction spectra of the triangle–rod dimer nanostructure with varying the gap distance d and the fixed center offset g = 0 nm. The constant c equals to the vertical distance between the center and the side of notched triangle nanoslice.
