· Rb2SeCl6

Rb2SeCl6 is an inorganic halide ceramic compound composed of rubidium, selenium, and chlorine. This material belongs to the family of double halide perovskites and related structures, which are primarily of research interest for optoelectronic and photovoltaic applications due to their tunable bandgap properties and potential for light absorption and emission. While not yet widely deployed in commercial products, rubidium-based halide ceramics are investigated as alternatives to lead halide perovskites in solar cells and scintillation detectors, offering potential advantages in stability and reduced toxicity concerns.
