Rb2LiErCl6

Rb2LiErCl6 is a halide perovskite ceramic compound containing rubidium, lithium, erbium, and chlorine elements. This is a research-stage material primarily investigated for optical and photonic applications, particularly in the rare-earth doped ceramic family where erbium provides luminescent properties. Engineers would consider this material for advanced photonic devices, solid-state laser systems, or scintillation applications where rare-earth ions enable specific wavelength emission, though it remains largely in the development phase rather than established industrial production.
