In this work preparation and characterization of a zinc metal target in isopropanol liquid at room temperature is carried out by PLAL technique at different laser fluency. The effect of laser fluencies during laser ablation process on the structure properties of the NPs is investigated.
We have use UV-visible spectroscopy, Atomic force microscopy and Energy dispersive X-ray (EDX) was used to evaluate the bulk atomic composition of NPs. The absorption peak of samples prepared in isopropanol solution is seen to be substantially blue shifted relative to that of the bulk zinc oxide due to the strong confinement effect. The technique offers an alternative for preparing the nanoparticles of active metal. The morphological investigation, carried out using (AFM), showed thatthe root mean square roughness is increased and the grain size of the obtained NPs are found to increase with the laser fluency.The use of isopropanol as solvent yielded spherical nanoparticles of 30–60 nm.
