Na2YF6

Na2YF6 is an inorganic fluoride ceramic compound composed of sodium, yttrium, and fluorine, belonging to the family of rare-earth fluoride materials. It is primarily investigated in photonics and luminescent applications, particularly as a host matrix for lanthanide dopants in upconversion materials used for biomedical imaging, optical sensing, and solid-state laser systems. This material is notable for its low phonon energy and high optical transparency, which make it suitable for efficient energy transfer in rare-earth doped systems, offering advantages over some oxide-based alternatives in applications requiring minimal non-radiative losses.
