Abstract

Tantalum disulfide (TaS2) nanoplatelets were produced by laser ablation of a TaS2 target under an argon atmosphere. The nanoplatelet dimensions and morphology were characterized by transmission electron microscopy and x-ray diffraction. The effect of the ablation laser power density on the size distribution of the nanoplatelets was studied. The TaS2 nanoplatelets were prone to oxidation upon exposure to air but could be stabilized by using 3-mercaptopropionic acid as the capping agent.
