The synthesized samples are Vernier single phases with a stoichiometry assigned to Lu10O9F12, as demonstrated by X-Ray powder diffraction. The structural disorder of the host matrix significantly affects the optical emission spectra of the lanthanide doped samples as well as their vibrational spectra. The observed bandwidths of the FTIR spectrum and Raman scattering of the undoped sample are consistent with a very disordered nature of the host. From an analysis of the emission spectra of the Eu3+ doped sample it was found that different sites accommodating the lanthanide ions are present in the crystal structure. The Pr3+ and Ce3+ doped oxyfluoride samples show radioluminescence emission both in the UV and visible regions.
