Two-photon luminescence imaging of PSS-stabilized GNRs immobilized on thiol-derivatized glass coverslips. TPL signals were filtered through a bandpass filter with cutoffs above 500 nm and below 600 nm. (a), (c) λLPR = 715 nm; (b), (d) λLPR = 835 nm. (a), (b) TPL signals from GNRs using unpolarized excitation at 715 nm with an output power of 3 mW. (c), (d) TPL signals from GNRs using unpolarized excitation at 835 nm with an output power of 3 mW.
