In this paper the effects of ablation energy on the formation of tantalum-oxide nanoparticles via liquid pulsed laser ablation are investigated. For this purpose using pulsed laser ablation of a Ta metal plate Tantalum-oxide (Ta2O5) nanoparticles were synthesized in deionized water which the beam of a Q-switched Nd:YAG laser is employed to irradiate the tantalum target in water. We consider for 532 nm laser wavelengths, the spot sizes of laser pulse on the target surface is 14.39 μm at 6-ns pulse width whiles the samples were prepared with laser pulse energy of 0.3, 0.6 and 0.9 w. In order to investigate the effect of ablation energy on crystalline structure, characterization of products and morphological properties X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy are used, in addition the optical properties of the nanoparticle solution were examined at room temperature by a UV-Vis absorption spectrophotometer. The results show that the tantalum-oxide nanoparticles were found to be orthorhombic crystalline structure with sphere shape with average diameters of about 20 to 30 nm, which the size of them depends on the laser pulse energy so that the size distribution of generated nanoparticles is decreased by increasing the laser pulse energy.
