BiSe nanofilm has exhibited many promising potentials application in the field of photo-to-heat conversion. A highly-efficient photo-to-heat conversion system of Ag/BiSe composite nanofilm is successfully fabricated through laser direct writing (LDW) technique. The localized heat induced by laser simultaneously achieve Ag particles synthesis, transfer and patterning in a single processing step. The thermal reaction process includes the forming of nanoparticles based on the process of the thermal reduction, laser ablation, sputtering deposition and so on. The thermal storage capability and photothermal conversion stability have been greatly improved through preventing the heat from loss and efficient LSPR enhancing. The photothermal conversion mechanism of composition film is discussed in detail. This work suggests that the laser-assisted transfer technique give rise to a new expectation of functional composite nanofilm application for energy conversion.
