SURFACE MORPHOLOGY AND OPTICAL PROPERTIES OF CUBIC-ZINC SULFIDE (C-ZNS) THIN FILMS

Cubic zinc sulfide (c-ZnS) thin films have been prepared using dip-coating technique. X-ray diffraction pattern revealed cubic phase with the preferred (111) plane in ZnS films. Scanning electron microscope (SEM) analysis showed the granular shaped type of surface texture. The energy dispersive X-ray method indicated an excess of zinc. UV-Visible spectroscopy is used to measure the transmittance of thin ?lms which is found to be superior to 80 %. These experimental results showed that the as-grown ZnS nanoparticles were of high purity.
