Laser cutting machine found that with the increase of concentration of the surfactant sodium dodecyl sulfate and the decrease of the laser power, the size of the silver nanoparticles and smaller range.
Choose appropriate wavelength of laser irradiating make the gold particle size decreases after ablation of new technology.
Is easy to cause the resonance absorption and the photon energy rapidly converted into heat energy, of nanoparticles in particle temperature rise sharply, produce blowout, still exists the accumulation of the particles in the solution at the same time when blowout and the aggregate balance, particle size small.
