  • Abstract

    A series of sulfur nanoparticles (SNPs) was synthesized by wet chemical precipitation method. In this process the initial precursor sulfur powder was heated with poly ethylene glycol-600 (PEG-600) and each of six imidazolium protic ionic liquids(PILs) such as 2-methylimidazolium lactate ([2 mim] CH3CH(OH)COO-), 1-ethylimidazolium lactate ([1eim] CH3CH(OH)COO-), 1-butylimidazolium lactate([1bim] CH3CH(OH)COO-), 2-methylimidazolium glycolate ([2 mim] CH2(OH)COO-), 1-ethylimidazolium glycolate([1eim] CH2(OH)COO-),1-butylimidazolium glycolate([1bim] CH2(OH)COO-) individually for separate process. Where the imidazolium PILs act both as solvent as well as stabilizer. The obtained SNPs are having different morphology and are characterized by UV, IR, XRD, TGA, DTA and SEM with EDAX analysis. Using one of the synthesized SNPs, ZnS and CdS semiconductor nanomaterials were prepared and characterized by XRD and SEM with EDAX analysis.
