Pd²⁺ (x = 0, 0.02 and 0.04) co-doped with Zn_0.98-xMn_0.02S (Mn²⁺:ZnS) nanoparticles were successfully synthesized by a simple co-precipitation method. The influence of the Pd²⁺ on the structural and morphological was investigated using the powder X-ray diffraction (XRD) pattern and Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM) images. XRD pattern proved the formation of the single-phase cubic structure for the Pd²⁺ (x = 0, 0.02 and 0.04) co-doped Mn²⁺:ZnS samples. The average particle size of the Mn²⁺:ZnS samples were identified to be ~1.75 nm from the XRD results. Fourier transform infrared (FTIR) spectra confirm the presence of vibrational modes of the ZnS with Mn²⁺ and Pd²⁺ ions in the samples. Red shift of the absorption band was observed and the 40% enhancement in the optical transmittance behavior was estimated for the Pd²⁺ co-doped Mn²⁺:ZnS samples in the UV–Visible analysis. Photoluminescence (PL) emission spectra exhibit increased intensity in the visible region and decrease in the UV region for the Pd²⁺ co-doped Mn²⁺:ZnS samples and these improved behavior of the samples were highly preferable for the optical device applications.

通过简单的共沉淀法成功合成了共掺杂Zn _0.98-x Mn _0.02 S（Mn ²⁺：ZnS）纳米粒子的Pd ²⁺（x = 0、0.02和0.04）。使用粉末X射线衍射（XRD）图案以及扫描电子显微镜（SEM）和透射电子显微镜（TEM）图像研究了Pd ²⁺对结构和形态的影响。XRD图谱证明了Pd ²⁺（x = 0、0.02和0.04）共掺杂Mn ²⁺：ZnS样品的单相立方结构的形成。Mn ²⁺的平均粒径XRD结果表明：ZnS样品约为1.75 nm。傅里叶变换红外（FTIR）光谱证实了样品中ZnS含Mn ²⁺和Pd ²⁺离子的振动模式。在紫外可见分析中，观察到Pd ²⁺共掺杂的Mn ²⁺：ZnS样品的吸收带发生红移，并估计其光透射率行为提高了40％。对于Pd ²⁺共掺杂的Mn ²⁺：ZnS样品，光致发光（PL）发射光谱在可见光区域显示出增强的强度，在UV区显示出减小的特性，这些改进的行为对于光学设备应用是非常可取的。
