Device for nanoparticle synthesis by pulsed laser ablation in a liquid flow

摘要

A useful model relates to the production of nanoparticles by pulsed laser ablation in liquids, in particular, and can be used to produce nanoparticles of various materials, both metallic and nonmetallic. The device comprises a flow cuvette for placing a target having an entrance window for laser radiation, a reservoir with a source solution and a reservoir with a solution of nanoparticles, a peristaltic pump and a particle concentration monitor. It is also equipped with a micro-flowmeter, two collet chokes, a flow velocity pulsation dampener, a forward flow crane, a return flow crane and a target fastening assembly, and longitudinal channels for flow distribution in the side walls of the cuvette body. In the bottom of the hull, there is a central channel in which a target attachment assembly is provided, in the form of a lid, fixed on the bottom of the central channel. In this case, one channel for distributing the flow through the choke, the micro-flowmeter and the peristaltic pump is hydraulically connected to the reservoir with the initial solution. The second channel for distributing the flow through the second nozzle, the particle concentration monitor and the forward flow cock is hydraulically connected to the reservoir with the nanoparticle solution, and the reservoir with the nanoparticle solution and the reservoir with the initial solution are hydraulically connected through the return flow valve. The device allows to obtain a laminar flow in the working volume of the cuvette with two methods of flow of liquid in the system - direct and return. 1 yl.
