Application and synthesis of ultrafast laser-based nanoparticles and doped 2D material

Ultrafast Laser Ablation Synthesis in Solution (LASiS) is a technique used to create nano particle inks by focusing an ultrafast laser into a bulk material submerged in a solution. This process offers a greener and inexpensive solution to creating nanoparticles with a very small size distribution. Limited tunability of average nanoparticle size, phase, concentration and absorbance spectrum has been shown through changes in laser parameters as well as preparation techniques. Our group was the first to show that this method can be used to create intercalation-doped 2D material where the dopant is a material of interest. Intercalation doping of 2D materials has the potential to generate a new class of materials with unique novel properties. 2D material production was successfully performed by using bulk materials and a polymer. The materials used for doping include Titanium dioxide, gold, and galfenol whereas the produced 2D sheets were of Graphene and Molybdenum disulfide (MoS2). In this work we will show how the nanoparticles doping of the 2D material can modify and tune the intrinsic properties of the 2D material through this technique.
