· JVASP-23114· KEr3F10

KEr3F10 is a rare-earth fluoride ceramic compound composed of krypton, erbium, and fluorine. This material belongs to the family of rare-earth fluorides, which are investigated primarily for optical and photonic applications due to their ability to host rare-earth ions for luminescence and laser functionality. While not widely established in high-volume industrial production, rare-earth fluoride ceramics like KEr3F10 show promise in specialized optical systems and represent an active research area for next-generation photonic devices where transparency, thermal stability, and rare-earth doping compatibility are critical.
