1. Introduction. Zinc oxide (ZnO) is an important semiconductor material because it possesses piezoelectric properties, wide band gap (3.37 eV), and large exciton binding energy (60 meV) .It can act as efficient photocatalyst, which can induce redox-processes owing to the electronic transitions between filled valence band and an empty conduction band .
We prepared Zinc oxide nanomaterial employing PLA (pulsed laser ablation) technique. A pure Zn target was immersed in ultra-pure water (UPW) and it was subjected to several pulses (1st. and 2nd. harmonic) of the pumping Nd: YAG laser. The influence of changing laser's wavelength (1064, 532) nm on the characterization of the produced nanoparticles was studied.
Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications.
