· Tl4CdI6

Tl₄CdI₆ is a ternary halide semiconductor compound composed of thallium, cadmium, and iodine. This material belongs to the family of metal halide semiconductors and is primarily of research and development interest rather than established commercial use. Potential applications include radiation detection, photovoltaic devices, and optoelectronic sensors, where its bandgap and halide structure may offer advantages in detecting gamma rays, X-rays, or visible light; however, the material remains largely experimental and faces challenges related to thallium toxicity and stability that limit widespread industrial adoption compared to more mature alternatives like CdTe or perovskite semiconductors.
