Fabrication of graphene based on Q-switched Nd:YAG laser ablation of graphite target in liquid nitrogen

In this work, a novel technique is presented for the graphene fabrication based on the pulsed laser ablation of graphite target inside the cryogenic liquid using the pulsed nanosecond Q-switched Nd:Y3Al5O12 (Nd:YAG) laser at 1064 nm. Single-stage fabrication process is taken into account as a remarkable advantage without need to high vacuum devices and additional chemical components. The synthesis process is controllable by changing the laser properties and the irradiation conditions accompanying easy collection of the products. [GRAPHICS] (C) 2012 by Astro, Ltd.
