摘要: We report a simple biomolecule-assisted synthesis of ZnS nanostructured spheres assembled from nanocrystals with the controllable crystal phase and morphology. l-Cysteine, biomolecule, was used as sulfur source played key role in formation spheres. various nanocrystal building blocks, such nanosheets, quantum dots, nanorods, multimorphology nanocrystals, were successfully prepared by this method. The could be controlled introducing ethanolamine or ethanediamine surface-modifying reagent synthetic system. hexagonal obtained mixed solvents water at temperature low 95 °C. growth mechanism nanorods proposed. optical properties investigated ultraviolet−visible (UV−vis) absorption photoluminescence (P...
