| Description | Journal: Journal of Physics: Conference Series In this study, an easy and a rapid method has been used to prepare nanoparticles employing the laser ablation technique in Double Distilled Deionized Water (DDDW). Lasers with three different have been used. The laser ablation of a (Au core @ Ag shell) system shows the best ablation at wavelengths of 1064 and 355 nm in DDDW solution with resulting Grain size less than (20 nm).This is the best result for obtaining the size near Quantum Dot (Q.D.) of the Ag @ Au NPS system. The TEM, AFM and statistical distribution of Grain size have been used to analysis morphological properties. The absorption peak shows IR shift for Au @ Ag system, that leads to growth large grains. This indicates that Ag-shell more effective than Au-core at (532,355) nm wavelengths. Some of the optical parameters, such as refractive index (n) and extinction coefficient (k), have been calculated for the prepared nanoparticles collide. TEM shows the formation (Core -Shell) clearly, and the form of NPs can almost have a spherical shape with size < 20 nm. The gold (Au-shell) is more effective than Ag-core.The colloidal nanoparticles have been used as in biological applications to kill or inhibit E. coli and Staph bacteria. |
