Abstract

Phase-pure orthorhombic α′- and monoclinic β-Sr2SiO4 and its Ce3+- or Eu2+-doped versions are prepared by reaction of stoichiometric amounts of SrCO3, SiO2, CeO2 or Eu2O3 in the presence of 1 wt% H3BO3 or 1-50 wt% SrCl2 as fluxes in different atmospheres (1200-1400 °C, 4 h; in air, vacuum, 5% H2/N2, or 25% H2/N2).
