Chemically stable and transparent K2NaLuF6 single crystals doped with Tm3+ ions were grown by the micro-pulling down method. X-ray diffraction measurements showed that the as-grown crystals possess cubic structure with Fm3m space group. The radio- and photo-luminescence spectra of the grown crystals were measured in the vacuum ultraviolet (VUV) and ultraviolet (UV) regions. Tm:K2NaLuF6 showed high emission intensity at 188 nm in the radio- and photo-luminescence spectra (exc = 159 nm).
