Fabrication of Different Photoluminescence Nanostructures of Cadmium Sulfide to Quickly Identify Heavy and Carcinogenic Metals Cadmium and Lead

Year: 2025
Type: article
Abstract: In this study, the fabrication of photoluminescent cadmium sulfide nanostructures with various dimensions was explored to achieve rapid detection of the heavy and carcinogenic metals cadmium and lead. These metals have become increasingly significant in scientific research—particularly in environmental and health sciences—due to the serious hazards they pose to both human health and the environment. The focus of this work was to develop a fast and sensitive method for identifying these hazardous metals using nanostructured materials. To accomplish this, zero-dimensional, one-dimensional, and two-dimensional cadmium sulfide nanostructures were synthesized, and their photoluminescence characteristics were subsequently examined. Photoluminescence, the emission of light from a material upon optical or electrical excitation, is a key property that can be employed for the detection and identification of specific substances. The ability of these nanostructures to rapidly detect the carcinogenic heavy metals cadmium and lead was assessed and compared. Photoluminescence spectroscopic analysis—through evaluation of the intensity and wavelength of the emitted light—demonstrated that these nanostructures are capable of distinguishing between heavy metals and carcinogenic agents. The results indicate that producing photoluminescent cadmium sulfide nanostructures with different dimensionalities offers an effective approach for the quick and sensitive identification of cadmium and lead. This method provides greater speed and accuracy than conventional detection techniques and holds potential for use in laboratory, industrial, and medical applications.
