Abstract EN
Gold(Au), Platium (Pt) and Gold –Coated Platinum (Au@Pt) ultra Fine(UF) nanoparticles (NPs) were preperd by Pulsed Laser Ablation in Liquids method with (Q-switched, 1064 doubled frequency-Nd: YAG).
The laser ablation of Au ,Pt metal plates and (Au@Pt) has been performed by immersing these metal plates in two different liquid deionised water (DIW) and ethanol alcohol .
(PLAL) process preformed with 100 pulse energy of 700 mJ and liquid depth is 2cm.
The nanoparticles of the gold element were coated with platinum(Au@Pt) in two steps.
The nanotubes of the gold element were first examined and the platinum metal was then immersed in the liquid from the first step.
The formation efficiency of PLAL process was quantified in term of the absorption spectrum peaks.
The absorption spectra ( Pt) in DIW shows a sharp and single peak around 234nm,and (Au@Pt) shows a sharp and single peak for Au at 516nm and for Pt 221nm.The TEM images show that the nanoparticles are rather spherical in shape .While the average size for all the samples was in rang from(2-5)nm .There was an increase in size when using ethanol alcohol.
Changing the way of the fluid environment is a simple and flexible way to control the size and strength of Au and Pt and (Au@Pt) colloidal nanoparticles.
