The LSPR exhibits a light-controlled red-shift of more than 100 nm, but only under continuous illumination. It is also possible to return to the starting LSPR value by washing the nanorods with cetyltrimethyl ammonium bromide solution.falsegold nanorods | light-induced | longitudinal surface plasmon resonance | optical microscope | tuningConference PaperDecember 201909013902cpConference Proceeding0
