Doping Eu2+ is challenging in some materials because of the stability of Eu3+. An alternative method for doping divalent europium was explored in the phosphor Sr3-xB2O6:Eux. Here, samples prepared from SrCO3 and H3BO3 are compared to samples prepared by using SrB4O7:Eu as a precursor. Samples prepared using the SrB4O7 precursor had a greater amount of divalent europium than samples prepared by traditional means, based on relative emission intensities. Similar methods could be applied to dope divalent europium into compounds that traditionally have only incorporated trivalent europium.
