这项研究旨在报告水溶性Mn掺杂的ZnSe-Zns合金量子点（QD）的热液合成，其中锰（MN2+）是发射中心。合金组成由ZnSE的混合比控制：Mn和Zns：Mn前体溶液。清楚地观察到来自MN2+中D-D转变的光致发光（PL）带清楚地观察到。随着合金QD中Zns量的增加，吸收能量向更高的能量转移，表明合金QD的成功制备也会增加，而MN PL强度也增加了。
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.
