Used in the preparation of cadmium-based semiconductor materials, particularly in the synthesis of cadmium telluride (CdTe) thin films for solar cells. Employed in electrochemical processes as a source of cadmium ions. Serves as a reagent in organic and inorganic synthesis, especially in laboratories for iodide exchange reactions. Applied in the production of phosphors and scintillation detectors due to its ability to form compounds that emit light when exposed to radiation. Also used in some types of liquid crystal displays and optical coatings for specialized industrial applications.
