Preparation of ZnS:Mn Nanoparticles in Reverse Micellar Systems and Their Photoluminescent Properties

Abstract

The photoluminescence from Mn²⁺-doped ZnS (ZnS:Mn) nanoparticles prepared in an AOT/isooctane reverse micellar system was investigated. The composition (Mn content) and photoluminescent properties of the nanoparticles depend on the composition of the feed solution and the water content (W_o) of reverse micellar solution. The emission intensity from Mn²⁺ ions at 580 nm depends mainly on the Mn content in the nanoparticles rather than the nanoparticle size, when the nanoparticle size is controlled by varying the W_o value at a constant feed composition of Zn and Mn.
