ABSTRACTHybrid organic/inorganic nanocomposites composed of zinc hydroxide and surfactant molecule, and/or zinc oxide nanoparticles were fabricated using pulsed laser ablation of zinc in aqueous solutions of various surfactants. A Zn plate was ablated by a pulsed Nd:YAG laser in four types of surfactant solutions with different concentrations. Zinc oxide nanoparticles with average diameter of 10–40 nm were obtained in cationic, amphoteric and nonionic surfactant solutions. Unique layered organic/inorganic nanocomposites composed of zinc hydroxide layers and surfactant molecules were obtained in aqueous solutions of the anionic surfactants, sodium alkyl sulfate (CnH2n+1SO4-·Na+). The carbon number, n, in the alkyl sulfate family is very important for the formation and structure of the layered nanocomposites. The layered organic/inorganic nanocomposite can be obtained only in the specific sodium alkyl sulfates (n = 12, 13, 14 and 16) and the layer spacing of the nanocomposites increased with n from 26.8 Å to 42.0 Å. It is shown that the structures of ZnO nanoparticles and layered organic/inorganic nanocomposites can be controlled by the type of surfactants in solution.

This work is focused on studying the effect of liquid layer level (height above a target material) on zinc oxide nanoparticles (ZnO and ZnO2) production using liquid-phase pulsed laser ablation (LP-PLA) technique. A plate of Zn metal inside different heights of an aqueous environment of cetyl trimethyl ammonium bromide (CTAB) with molarity (10-3 M) was irradiated with femtosecond pulses. The effect of liquid layer height on the optical properties and structure of ZnO was studied and characterized through UV-visible absorption test at three peaks at 213 nm, 216 nm and 218 nm for three liquid heights 4, 6 and 8 mm respectively. The obtained results of UV–visible spectra test show a blue shift accompanied with decreasing the liquid level above the target due to the increase in ablation rate and particles production. This blue shift indicates getting a smaller size of nanoparticles and the quantum confinement property of nanoparticles. Also the FTIR transmittance spectra of ZnO2 nanoparticles prepared in these states show a characteristic ZnO absorption at 435 cm−1 – 445 cm−1.

Laser Ablation Technique

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. The results obtained from studying the structure, topography, and morphology of the product showed that the particles have a hexagonal shape. Also, changing the wavelength of the laser from 532nm to 1064nm leads to size reduction and density increasing of the nanoparticles.
