ABSTRACT=Plasmonic nanostructures emerged as an appealing approach for black metal absorbers (BMAs) to provide significant light absorption. We present the simple and rapid fabrication of BMAs using laser-induced forward transfer of silver nanoparticles (AgNPs). Randomly distributed plasmon silver nanostructures with multiscale were produced simultaneously during laser transfer, providing significant light absorption and antireflection features. The laser-transferred BMAs exhibit excellent absorption capacity of a value over 96%, and a minimum reflection of 0.38%. A high scanning speed of 10 m/s was used that can complete the LIFT process within 2 s for a 1 cm2 area. The nearfield light confinement is discussed in terms of the morphology of the obtained nanostructures. Photothermal conversion with macroscale temperature rising was demonstrated for the laser-induced BMAs. The results indicated that laser-induced forward transfer (LIFT) is an effective method for the industrial production of BMAs with excellent absorption capacity.
