· JVASP-136629· RbYF4

RbYF4 is a fluoride-based ceramic compound combining rubidium, yttrium, and fluorine. This material belongs to the family of rare-earth fluoride ceramics, which are primarily of research and specialized industrial interest rather than mainstream engineering applications. RbYF4 is investigated for optical and photonic applications, particularly in laser systems and scintillator technologies where its fluoride composition can offer favorable transparency and luminescence properties; it may also be explored for solid-state laser host materials and radiation detection systems where rare-earth doping is employed.
