Abstract
Nanoparticles of ZnS have been synthesized via radio frequency magnetron sputtering technique. Selected area electron diffraction patterns confirmed the nanocrystalline cubic phase of ZnS. TEM micrographs of the thin films revealed the manifestation of ZnS nanoparticles (3.00 – 5.83 nm). UV-VIS-NIR spectrophotometric measurements showed that the films are highly transparent ∼ 90 % with a blue shift of absorption edge. The particle size calculated from the shift of direct bandgap (3.89–4.44 eV) due to quantum confinement of nanoparticles lying in the range 3.23 – 5.60 nm, which well support the TEM results. The photoluminescence spectra of the films showed sulfer vacancy in the films and the EDX results also supported these results.
