a Schematic of 2,2′-BPD layer on gold illuminated by white light. b Nanocaps formed within illuminated area after 10 h of white light exposure (illuminated area seen as central brighter region). c Single nanocap dark-field scattering spectra which redshifts with time during irradiation. d, e SEM images of photocreated nanocaps on Au from (d) top and (e) 45° angle view. inset: SEM image of a single nanocap. f AFM profiles of several nanocaps, inset: AFM topographic image, greyscale shows height.
