(a) Representative infrared images of the photothermal response in HG/xNR samples (digital photographs are shown in insets). The samples were irradiated at a constant power (∼85 mW). The exposure time was 5 s. The dotted circles indicate the sample boundaries. The local temperature increase is indicated by a rainbow colour scheme in the infrared images. (b) Temporal temperature profiles (t=5 s) extracted from the infrared images across the bulk HG/xNR samples with various concentrations of AuNRs. (c) The peak temperature increases with increasing AuNR concentration.
