Rb2NaSbBr6 is a halide perovskite ceramic compound containing rubidium, sodium, antimony, and bromine. This material belongs to the emerging class of double perovskites—a research-focused family of inorganic compounds investigated as alternatives to lead-based perovskites for optoelectronic and photovoltaic applications. While not yet widely commercialized, halide double perovskites like this are studied for their potential to combine tunable bandgaps, improved stability, and reduced toxicity compared to conventional perovskite semiconductors, making them candidates for next-generation solar cells, LEDs, and radiation detection devices.
