XRD and HRTEM Study of Zirconia Nanoparticles Synthesized by Laser Ablation

Abstract:

To investigate doping-free zirconia, pulsed laser ablation technique was applied to synthesize pure zirconia nanoparticles. Various experimental parameters were investigated by means of microscopic, spectroscopic and diffractmetric techniques to reveal morphology and production yield. It is successful to form cubic and monoclinic phases at nanometer-scale fine particles. The cubic phase has relatively small lattice parameters than the stabilized zirconia.
