摘要：

This study aims to report the hydrothermal synthesis of water-soluble Mn-doped ZnSe-ZnS alloy quantum dots (QDs), wherein manganese (Mn2+) serves as an emission center. The alloy composition was controlled by the mixing ratio of ZnSe:Mn and ZnS:Mn precursor solutions. The photoluminescence (PL) band originating from the d-d transition in Mn2+ was clearly observed. With an increase in the amount of ZnS in the alloy QDs, the absorption onset energy shifted toward higher energy, demonstrating the successful preparation of alloy QDs, and Mn PL intensity increased as well.
