A study on the defects structure of colloidal ZnS using Ag surface plasmons

► Effects Ag surface plasmons (SPs) on the defects of ZnS. ► Introducing defects to ZnS. ► Well resolved, enhanced, and red-shifted PL emissions from ZnS on Ag. ► Energy transfer between the absorption bands of the inter-band states and the surface states of ZnS by Ag SPs.
