    Synthesis of Eu and Dy doped Sr3B2SiO8 using solid state reaction and investigation of radio and photoluminescence properties of these materials
    (2013) Şabikoǧlu I.
    Sr3B2SiO8 host material doped with separately Eu3+, Dy3+ synthesized by conventional solid state synthesis methods at 1100 °C. According to the results of XRD, samples have both of the Sr3B2SiO8 phase and the SrSiO3 phase (Multi-phase MP). Although there is significant amount of impurity concentration, expected energy transitions were obtained from the samples which are doped with Eu3+ and Dy3+. Both samples were performed to the radioluminescence (RL) and photoluminescence (PL) measurements. Measurement results, they were both in harmony with each other. Eu: Sr3B2SiO8 (MP) phosphor has 5D0 → 7Fj (j = 0, 1, 2, 3 and 4) transitions and Dy: Sr3B2SiO8 (MP) phosphor has 4F9/2 → 6HJ (j = 9/2, 11/2, 13/2 and 15/2) transitions. Dy:Sr3B2SiO8 (MP) phosphor synthesized by conventional solid state synthesis method and the RL and PL properties were examined for the first time. © 2012 Elsevier B.V. All rights reserved.
