Description
Summary:Dependences of the morphology and optical properties of silicon nanostructures on the laser ablation synthesis conditions, namely, the laser focusing conditions, laser pulse repetition rate, and temperature and composition of the solution, were established. The obtained regularities were used to develop a method for formation of Si–Ag and Si–Ag–Cu hybrid metal–silicon nanostructures. The obtained broadband absorption of the Si–Ag–Cu nanoparticles is promising for application in nanofluids for photothermal energy conversion of solar radiation.
