Synthesis, analysis and applications of nanoparticles prepared by laser ablation in liquids

Laser synthesized colloidal solutins of TiO2, ZnO, Au and Ag nanoparticles has been used for incorporation into different materials with atmospheric pressure plasma jet (APPJ) and for applications in photocatalysis. Laser synthesis of nanoparticles is based on a process of laser ablation of metallic targets in liquids [1]. By laser ablation in liquids a synthesis of nanoparticles from wide variety of materials (metals, semiconductors, alloys, glass) is possible which makes it as versatile synthesis technique [2, 3]. It is known as 'green' synthesis method because there are no chemicals involved in the synthesis and chemical reaction byproducts which is the main advantage of this method over the standard chemical methods where often additional purification is needed [4]. Treatment and incorporation of nanoparticles into materials such as PVC polymers by atmospheric pressure plasma jet (APPJ) will be discussed [5, 6]. Photocatalytic activity on different dyes of ZnO and TiO2 nanoparticles has been studied. One of the topic of this talk is development and verification of a quantitative method for determination of concentration of nanoparticles synthesized by laser ablation in liquids.
