Investigation of Ta nanoparticles characteristics produced by laser ablation method

Abstract

In this paper the characteristics of Tantalum nanoparticles produced by laser ablation method is investigated experimentally with a first harmonic of a Q-switched Nd:YAG laser of 1064 nm wavelengths at 6 ns pulse. Spherical nanoparticles of Ta and tantalum oxide have been produced successfully by using a Ta target in ethanol. The fluency of laser was 0.9 J/cm2. The samples were characterized by using transmission electron microscopy (TEM), photo luminescence (PL), X-ray diffraction (XRD) and absorption spectroscopy analyses. The size of produced nanoparticles is mainly in the range between 10–20 nm, structural and phase compositional of produced Ta nanoparticles.
