· JVASP-53045· YbNaF4

YbNaF4 is a rare-earth fluoride ceramic compound combining ytterbium, sodium, and fluorine, typically studied as a host material for luminescent and photonic applications. This material is primarily investigated in research contexts for use as an upconversion phosphor and laser host, where rare-earth dopants enable conversion of infrared radiation to visible light and support coherent light generation. YbNaF4 is notable for its low phonon energy (characteristic of fluoride ceramics), which reduces non-radiative losses and makes it competitive with more common host materials like YVO₄ and YAG in specialized photonic and biomedical imaging applications.
