Abstract—
Laser synthesis of composite nanoparticles of perovskite BaTiO3 and Au nanoparticles has been carried out using laser ablation in water and aqueous solutions. Two approaches were used to this end. Within the first approach, a gold target is subjected to laser ablation in an aqueous colloidal solution of perovskite. In the second approach, a mixture of aqueous colloids of the components is irradiated by a laser. The synthesized particles have been investigated by optical spectroscopy, Raman spectroscopy, and transmission electron microscopy.
