The structure and spectral-luminescent properties of solid solutions in the PbF2–EuF3 and PbF2–ErF3 systems obtained by both solid-phase reaction and co-precipitation from solutions are investigated. Nanopowders of compositions Pb1-xEuxF2+x or Pb1-xErxF2+x with a size of 40 nm were obtained by co-precipitation. The boundaries of the existence of a solid solution at a high and low temperature are determined. The differences in the luminescence spectra for solid solutions obtained by different methods are studied.
