Abstract: Thiol-capped CdTe nanocrystals with cubic zinc blende structure were synthesised in aqueous solution by wet chemical route and microwave assisted method. A series of cadmium telluride (CdTe) nanoparticles capped with mercaptoacetic acid were prepared using different pH values. The synthesised nanoparticles have been characterised with Raman, FT-IR, ultraviolet visible (UV-Vis) absorption, fluorescence spectroscopy and X-ray powder diffraction (XRD) studies.

Keywords: cadmium telluride; CdTe nanoparticles; wet chemical route; microwave assisted method; optical properties; Raman aspectroscopy; infrared spectroscopy; thiol capped nanocrystals; nanotechnology.
