· Br10 Rb2 Pb4

Br₁₀Rb₂Pb₄ is a mixed-halide perovskite-related semiconductor compound combining bromine, rubidium, and lead elements. This is a research-phase material within the broader family of halide perovskites, which are being actively investigated for optoelectronic applications due to their tunable bandgaps and solution-processability. The compound represents an experimental composition exploring how alkali metal (Rb) incorporation and multi-halide systems can modify electronic properties and stability compared to conventional lead halide perovskites.
