STEM images and UV-Vis spectra of Au NS s of different shapes. a BF-STEM image of Au NRs of dog-bone morphology and HRTEM image in inset shows the single crystalline nature of NRs. b BF-STEM image of elongated tetrahexahedral Au NSs (inset is SEM image). c SEM image of Au BPs (inset is SEM image of single BP). d TEM image of Au spherical particles (HRTEM image in inset shows the polycrystalline nature of Au particles). e BF-STEM image of Au NMs. f UV-vis spectra of Au NSs of different shapes
