Microcrystalline anti-Stokes luminophores NaY1-x-y-zYbxEryLuzF4 were successfully obtained for the first time via hydrothermal synthesis. These compounds crystallize in the hexagonal crystal system, with the structural type beta-NaYF4. Addition of non-luminescent lutetium(III) ions was found to result in more than 2 times enhancement in up-conversion luminescence upon 980 nm excitation.
