a UV-Vis-NIR absorption spectra of the pristine and MD-Ag2Se films. b Simulated normalized electric field distribution of the MD-Ag2Se film. c Temperature-time curves of the MD-Ag2Se film under different light intensities; the inset illustrates the relationship between Tmax and light intensity. d Photothermal conversion efficiency η of the pristine and MD-Ag2Se films. e Temperature-time cycling behavior under repeated light on/off cycles. f Infrared thermal images of the MD-Ag2Se film patterned into an “HBU” shape under illumination at different times. g Temperature–time curves of the film under outdoor illumination. h Dependence of Tmax on the number of bending cycles.
