Ho Van Tuyen, Nguyen Manh Son, and Vu Xuan Quang, Structural behavior and Judd–Ofelt intensity parameter of Sr3B2O6:Eu3+ phosphor, Int. J. Mod. Phys. B 29, 1550235 (2015)

In this study, the Sr3B2O6:Eu3+ phosphors were synthesized using combustion process and the annealing treatment. Structural behaviors of the prepared phosphor were explored by using X-ray diffraction (XRD), Raman spectra analysis and optical characteristics were studied by excitation and photoluminescence spectra. The phonon sideband (PSB) spectrum associated with
7F0-5D2 excitation transition was used to estimate the electron–phonon coupling constant (g) and local structure of the Eu3+
ions with its surrounding ligands. Judd–Ofelt (J–O) intensity parameters obtained from emission spectra have been used to evaluate the local site symmetry around Eu3+ ions.
Keywords: Sr3B2O6, phonon sideband; Raman characteristic; Judd–Ofelt intensity parameters
