Laser-ablation-assisted sf6 gas decomposition for extensive and

Apr 01, 2019 · We present a safe, clean, convenient and easy-to-control method for extensive fluorination of graphene using laser-ablation-assisted decomposition of gaseous SF 6 molecules. The decomposition process is based on irradiation of a silicon target using a Nd:YAG laser (532 nm) in an SF 6 atmosphere. The reactive species produced in the plume above the silicon target are consequently responsible for fluorination of graphene placed in proximity to the plume.Get price
