Abstract

The present research investigates the use of a powerful lamp for the ablation of graphite, hexagonal boron nitride, and tungsten disulphide precursor powder in specialized ampoules. The technique is a one-step, cost-effective process that does not use any catalyst, templates or toxic-reagents and has the potential to be scaled-up. Each experiment has been repeated several times with varying reaction time. Nanoparticles produced were characterized using SEM, HRTEM, AFM, Raman Spectroscopy, XRD, EDS and EELS. Nanoparticles revealed high-crystallinity and high-purity which included graphene-like sheets from graphite, nano-onion and nano-plates from Boron Nitride, nano-web like structures and nanotubes from WS2 precursor powder.
