The current study deals with the structural, morphological, elemental, optical and photoluminescence behaviors of Ag⁺, Mn²⁺ dual doped ZnS quantum dots (QDs). The X-ray diffraction (XRD) and Transmission Electron Microscope (TEM) studies confirmed the cubic structure and size of the crystallites (~2 nm). The Scanning Electron Microscope (SEM) photographs portrayed the surface and morphological structure of prepared samples. Energy dispersive X-ray (EDX) and Fourier Transform Infrared Spectra (FTIR) ensured the presence of Zn, Ag, Mn and, S in the samples as per the anticipated stoichiometry ratio. The UV–visible spectra showed a red shift in optical absorption and band gap gets narrowed due to the incorporation of Ag⁺ ions. The size effect has overcome the quantum confinement effect in this case. Through photoluminescence (PL) studies, a weak UV emission and strong red wavelength emissions were received and discussed on the basis of sulfur vacancies. This red emission was dealt in terms of d-electrons transition between host and dopant ions.

当前的研究涉及Ag ⁺，Mn ²⁺双掺杂ZnS量子点（QDs）的结构，形态，元素，光学和光致发光行为。X射线衍射（XRD）和透射电子显微镜（TEM）研究证实了微晶的立方结构和尺寸（约2 nm）。扫描电子显微镜（SEM）的照片描绘了所制备样品的表面和形态结构。能量色散X射线（EDX）和傅里叶变换红外光谱（FTIR）可确保按照预期的化学计量比在样品中存在Zn，Ag，Mn和S。紫外可见光谱显示，由于Ag ⁺的引入，光吸收发生红移，并且带隙变窄离子。在这种情况下，尺寸效应克服了量子限制效应。通过光致发光（PL）研究，在硫空位的基础上收到并讨论了弱UV发射和强红色波长发射。根据主体离子和掺杂离子之间的d电子跃迁处理了这种红色发射。
