ABSTRACTCadmium based oxide and hydroxide nanocomposites material is synthesized by pulsed laser ablation of cadmium metal in the double distilled water. A piece of cadmium metal, placed on the bottom of glass vessel containing double distilled water, was irradiated with 1064 nm of pulsed Nd:YAG laser operating at 35 mJ/pulse energy and 10 ns pulse width for 30 minutes. Colloidal solution of produced Nanoparticles is found stable for two days. Fine white colored powder is obtained after drying centrifuged solution. UV-visible absorption of colloidal solution, XRD, TGA, DTA and FTIR of the powder is used for the characterization of material. Possible mechanism of synthesis and hydroxide to oxide transition is discussed.

TiOx/CdS composites were synthesized by CdS deposition on TiOx from aqueous solutions of Cd (CH3COO)2 and Na2S with and without addition of a stabilizing agent–Na2SiO3. Initial high-defective TiOx nanocrystalline powders were prepared by pulsed laser ablation (Nd:YAG laser, 1064 nm, 7 ns) of Ti target in H2O. Composites obtained exhibit absorption in the visible range up to 520 nm. On the example of Rhodamine C photodecomposition in water it was revealed that the nanocomposite TiOx/CdS powders obtained exhibit good photocatalytic properties when excited by visible light.

Fe@Au is a type of nanoparticle that contains magnetic Fe NPs core with a fine layer of Au NPs synthesized using the Pulsed Laser Ablation in Liquid (PLAL) Method. These Fe@Au NPs characterized by Atomic Force Microscope (AFM), Field Emission Scanning Electron Microscopy (FESEM), and UV-Visible Spectrophotometer. The result was obtained at different laser fluences (1.9, 2.2, and 2.5) J/cm2 with fixed pulse duration 5 ns, wavelength 532nm and number of pulse equal 100 pulsed. The obtained mean size of Fe@Au NPs at laser fluence (1.9, 2.2, and 2.5) J/cm2 was (63.65, 32.47 and 31.18) nm respectively. UV-Visible Spectrophotometer carves was showed a redshift toward longer wavelength by increasing particle size. Obtained results exhibited that the laser fluence plays a key role in the size, and dispersity of Fe@Au NPs.
