· JVASP-102421· K2RbPrI6

K2RbPrI6 is a mixed-halide perovskite ceramic composed of potassium, rubidium, praseodymium, and iodine. This is an experimental compound primarily of research interest rather than an established industrial material, belonging to the family of hybrid and inorganic perovskites that are actively investigated for optoelectronic and photonic applications. The material's notable features stem from its crystal structure and halide composition, which researchers explore for potential advantages in light emission, radiation detection, or scintillation compared to conventional single-cation perovskites.
