摘要： The present invention relates to a method for preparing nanoparticles by using laser and more particularly, a method for preparing nanoparticles by irradiating a laser beam to the mixture of a source material gas and a hexafluoride (SF6) catalyst gas, thereby improving the production yield of nanoparticles with energy saved. More particularly, the present invention provides the method for preparing the nanoparticles by using the laser wherein the laser beam of wavelength having the excellent energy absorption by the mixture gas of source material gas and catalyst gas is irradiated to the mixture gas so as to increase the reactivity of the source material gas with energy saved, which brings the effects of solving the problems of damaging environment due to the unreacted toxic source material gas incurred by the low production yield of the conventional nanoparticle preparation method and of making system complicated with the high cost when the discarded source gas is recovered and reused.
