Facile and Greener One Pot Synthesis of Zinc Sulphide Quantum Dots Employing Zinc based Ionic Liquids and their Photocatalytic Activity

Abstract

An economical and greener method for preparation of Zinc Sulphide (ZnS) quantum dots where zinc (metal M) containing ionic liquids (MILs), [Cnmim][ZnCl3], n = 4, 8, 16, have been used as precursor, template as well as solvent, is presented. ZnS Quantum dots (QDs) have been synthesized at room temperature by simple grinding method. The prepared QDs are characterized by X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), UV-Vis spectroscopy and Photoluminescence spectroscopy (PL). The XRD pattern of the investigated QDs suggest a zinc blende structure, where broadening of diffraction peaks with increase in alkyl chain length of MILs has been observed. The ZnS QDs are found to be spherical in shape with an average diameter of 1.5-5.0 nm, which varies with the length of alkyl chain of MIL. The application of prepared ZnS QDs towards the photocatalytic degradation of Rhodamine b under UV-light has also been investigated and discussed. The size, optical and photocatalytic properties of ZnS QDs are found to be dependent upon the length of alkyl chain of MIL. The present simple yet economical method of preparation and MIL dependent characteristics of QDs provides a new way to manipulate the properties at nanoscale.
