Synthesis of Eu and Dy doped Sr3B2SiO8 using solid state reaction and investigation of radio and photoluminescence properties of these materials
Abstract
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.
