ceramic

· JVASP-55643· YbRb4I6

YbRb4I6 is an iodide-based ceramic compound containing ytterbium and rubidium, belonging to the halide perovskite family of materials. This is primarily a research-phase compound studied for its ionic and photonic properties rather than an established engineering material in widespread industrial use. The halide perovskite family shows promise for solid-state lighting, radiation detection, and scintillation applications due to their tunable electronic structure and potential for efficient photon conversion.
