Laser synthesis of nanoparticles and applications

Laser synthesis of colloidal nanoparticle solutions, treatment of materials with atmospheric pressure plasma jet (APPJ) and their applications will be discussed in this talk. Laser synthesis of nanoparticles is based on a process of laser ablation of metallic targets immersed 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]. Laser synthesis of nanoparticles in liquids 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 impregnation of nanoparticles into materials such as polymers and cellulose by atmospheric pressure plasma jet (APPJ) will be discussed [5, 6]. 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 as well as their photocatalytic performances.
