Undoped and Metal Doped ZnS Nanoparticles by Precipitation Method
Keywords:
ZnS, nanoparticles, triethylamine, XRD, UV-VisibleAbstract
Nanoparticles of undoped and metal (Sn2+ and Cu2+) doped individually and combined with ZnS have been synthesised using triethylamine by precipitation. X-ray diffraction and optical absorption measurements have been made on nanoparticles of pure and metal doped ZnS. The studies reveal that the metal doped ZnS does not modify the cubic structure and the average crystallite size is found to be in the range of 6 - 15 nm. The undoped ZnS nanoparticles have higher optical absorption in the visible region than the metal doped ZnS and the allowed direct band gap energy is found to increase in metal doped samples.
