In this study, Cd_xZn_1-xS/PVA nanocomposites have been grown within polyvinyl alcohol (PVA) polymer matrix using the combined sorption of the cations by the successive ionic layer adsorption and reaction (SILAR) method. The effects of the different amount of Cd²⁺ and Zn²⁺ ions depending on the × value in Cd_xZn_1-xS, the number of reaction cycles, various cation sources, and the different reaction parameters on the formation mechanism and physical and chemical properties of nanomaterials were studied in this paper. The structural, optical analysis, chemical composition determination, morphology and the distribution of nanoparticles on the surface are characterized and studied using X-ray diffractometer (XRD), ultraviolet–visible (UV–Vis) spectrophotometer, scanning electron microscopy (SEM), energy-dispersive X-ray spectrometer (EDX) and optical microscopy. The particle size of the sample obtained after 5 cycles is larger than the particle size obtained at 2 cycles. The formation speed of nanoparticles is weak at room temperature and the particle size is in the range of 6.63–9.66 nm after 2 cycles and 8.89–22.7 nm after 5 cycles by SEM. The optical microscope results show that the distribution of elements by thickness is non-uniformity. The reason for non-uniformity is that the volume and surface energy are different. The band gap value of nanoparticles decreases as increasing the concentration of Cd²⁺ ions in Cd_xZn_1-xS nanostructures. The decrease in Eg depends on the growth of the particle size. This type of materials have great applications in photovoltaics, solar cells, and markers.

在这项研究中，Cd _x Zn _1-x S / PVA纳米复合材料已经通过连续离子层吸附和反应（SILAR）方法对阳离子的联合吸附在聚乙烯醇（PVA）聚合物基质中生长。Cd _x Zn _1-x中不同的Cd ²⁺和Zn ²⁺离子量取决于×值研究了纳米材料的S，反应循环数，各种阳离子来源以及不同的反应参数对纳米材料的形成机理和理化性质的影响。使用X射线衍射仪（XRD），紫外可见（UV-Vis）分光光度计，扫描电子显微镜（SEM），能量对结构，光学分析，化学成分确定，形态和纳米粒子在表面上的分布进行了表征和研究-色散X射线光谱仪（EDX）和光学显微镜。5个循环后获得的样品的粒径大于2个循环后获得的粒径。室温下纳米粒子的形成速度较弱，通过SEM观察，其粒径在2个循环后为6.63–9.66 nm，在5个循环后为8.89–22.7 nm。光学显微镜结果表明，元素的厚度分布是不均匀的。不均匀的原因是体积和表面能不同。纳米粒子的带隙值随着Cd浓度的增加而减小Cd _x Zn _1-x S纳米结构中的²⁺离子。Eg的减少取决于粒径的增长。这种类型的材料在光伏，太阳能电池和标识器中有很大的应用。
