This study reports the structural and optical properties of CdS/ZnTiO₃ nanocomposites prepared using a chemical bath and different titanate concentrations. Commercial ZnTiO₃ nanoparticles were introduced into a chemical bath that had been used to produce CdS semiconductor nanoparticles (NPs). Here, the growing CdS crystallites precipitated onto the suspended zinc titanate NPs. X‐ray diffraction patterns revealed that samples of CdS/ZnTiO₃ nanopowders were made of cubic ZnTiO₃ and hexagonal CdS wurtzite. The morphology of the particles was studied using transmission electron microscopy and scanning electron microscopy images. These images demonstrated the different characteristics of the CdS/ZnTiO₃ nanocomposites and their dependence on titanate concentration when placed into the CdS‐growing solution. Photoluminescence spectra showed three main emission bands for the electron transitions in the CdS/ZnTiO₃ composite. This composite produced three photoluminescence bands, the intensities of which depended on composite shape, which in turn depended on the relative concentrations of CdS and ZnTiO₃.

这项研究报告了使用化学浴和不同钛酸盐浓度制备的CdS / ZnTiO ₃纳米复合材料的结构和光学性质。将商业ZnTiO ₃纳米颗粒引入已用于生产CdS半导体纳米颗粒（NP）的化学浴中。在这里，正在生长的CdS微晶沉淀在悬浮的钛酸锌NP上。X射线衍射图谱显示CdS / ZnTiO ₃纳米粉的样品由立方晶ZnTiO ₃和六角形CdS纤锌矿制成。使用透射电子显微镜和扫描电子显微镜图像研究了颗粒的形态。这些图像证明了CdS / ZnTiO ₃的不同特性纳米复合材料及其在CdS生长溶液中对钛酸盐浓度的依赖性。光致发光光谱显示了CdS / ZnTiO ₃复合材料中电子跃迁的三个主要发射带。该复合材料产生三个光致发光带，其强度取决于复合材料的形状，而复合材料的形状又取决于CdS和ZnTiO ₃的相对浓度。
