Description
Summary:Silver nanoparticles (AgNPs) have attracted many researchers and scientist within the past decade due to their unique characteristics in physical, chemical, and biological properties compared to their macro scale. The AgNPs have been important subject of interest in applied science and material field and widely applied for various applications in the field of physics, chemistry, biology, environment, and medicine. The techniques usually used to synthesize silver nanoparticles are chemical, biological, and physical methods. However, chemical and biological methods still suffer from tedious sample pretreatment, contamination from additional agents during synthesis process, and quiet hazard and expensive. In this study, silver nanoparticles was synthesized using pulse laser ablation method. Experimentally, a high-purity silver plate (99, 95 %) was immersed in 25 ml pure aquades placed in a petri dish with a diameter 50 mm. A pulsed (Nd : YAG) laser (New Polaris II 1064 nm, max energy of 50 mJ, 7 ns) was focused on the gold sample target by a convex lens with a focal length of 30 mm. The laser repetition rate was 10 Hz, and the duration of laser bombardment was 13 hours. The results show that colloidal silver nanoparticles has yellowish colour. Furthermore, the produce silver nanoparticles have spherical shape with an averaged diameter size of tens nm. Detail results and discussion will be presented during presentation.
