Synthesis and optical characterization of ZnS,ZnS:Mn and (ZnS:Mn)_CdS core-shell nanoparticles

摘要

ZnS and ZnS:Mn nanoparticles and (ZnS:Mn)_CdS core-shell nanoparticles were synthesized by a chemical precipitation method,this method is simpler than previously reported methods for the same sort of nanoparticles.The nanoparticles obtained were characterized by XRD and spectroscopy techniques (fluorescence and UV-vis absorption).The core-shell nanoparticles present an improved fluorescence signal over ZnS and ZnS:Mn nanoparticles at 580 nm.
