· Pb4 I4 Cl4

Pb₄I₄Cl₄ is a lead halide perovskite-related semiconductor compound combining lead, iodine, and chlorine in a mixed-halide structure. This material is primarily studied in research contexts for optoelectronic applications, particularly as an alternative or complement to hybrid organic-inorganic perovskites, offering potential advantages in stability and tunability of electronic properties through halide engineering. The mixed halide composition allows bandgap tuning and may provide improved environmental stability compared to pure iodide perovskites, making it of interest for next-generation photovoltaic and light-emitting device development.
