· JVASP-91355· Tl4PbI6

Tl4PbI6 is a mixed-halide perovskite ceramic compound containing thallium, lead, and iodine, typically investigated as a semiconductor material for optoelectronic applications. This is primarily a research-phase material rather than an established industrial ceramic; it belongs to the family of lead halide perovskites and related structures that have attracted attention for photovoltaic and radiation detection applications due to their tunable bandgaps and high charge-carrier mobility. The inclusion of thallium distinguishes this composition from more common lead-only perovskites, potentially offering different electronic properties, though commercial adoption remains limited and material stability/toxicity considerations are relevant engineering constraints.
