摘要

An innovative design has been proposed to develop the synthesis of laser ablated gold nanoparticles in pure water, by co-radiation of Nd:YAG laser pulses and ultrasound waves. UV-VIS absorption spectroscopy illustrated the enhancement of the synthesis rate of the particles in the diversity of laser pulse energies applied in the presence of ultrasound waves. In addition, the proliferative effects of laser pulse energy on the synthesis rate and the size of particles were recognized as well. Emission spectroscopy of the induced plasma was utilized to justify the variation of the synthesis rate versus the applied operating conditions. Electron microscopy as a complementary technique confirmed the results of spectroscopic findings concerning the enlargement of nanoparticles by laser pulse energy.
