Synthesis And Property Of Compound Nanoparticles By Pulsed Laser Ablation Of Molybdenum Target

MoS₂ as the typical transition metal sulfide semeconductors, which have been proved to own great optical and electrical properties. They play an important role in lots of hot research area, especially in photoelectric conversion device. The synthesis and the application of inorganic fullerene nanoparticle just are the hottest. Transition metal carbides such as MoC have shown catalytic properties resembling group VIII metals in a number of hydrogen-involved reactions.But up to mow, the bottleneck emerge that be lack of structural diversity, limited synthesis methods and slow in performance improvement. Well it's belived the bacis solution for this bottleneck is the effective combination of the research of both materials synthesis and application,to design structure based on the requirement of its application.In this paper, some preliminary exploration and research has been carried out based on the requirements of newly materials synthesis methods and actual application performance would be focused. The main research results are as follows.1.We demonstrated that ns pulsed laser ablation of molybdenum target in liquid is a facile and rapid strategy for the fabrication of MoS₂. The crucial factors for control final nanostructures include solvent, surfactant, and sulfur resourse reactivity..2. We demonstrated that ms pulsed laser ablation of molybdenum target in reactive gas is a facile and rapid strategy for the fabrication of MoS₂ FL-NPs. The crucial factors for control final nanostructures include laser intensity, cooling rate, and gas reactivity. The MoS₂ FL-NPs show excellent photoresponse property at high temperature. We believe that this strategy can be expanded to other material systems for the synthesis various refractory-metal-sulfide nanostructures. Moreover, the stable photoresponse under high temperatures demonstrate the feasibility of using MoS₂ FL-NPs for heat-resistant photodetector and photoelectric switch.3. We demonstrated that ns pulsed laser ablation of molybdenum target in n-hexane is a facile and rapid strategy for the fabrication of MoC NPs. The crucial factors for control final nanostructures include laser intensity, carbon resourse.
