What is Influence of Ba2+-doping on structural and luminescence properties of Sr2SiO4:Eu2+ phosphors about?
Ba 2+ -doped Sr 2 SiO 4 :Eu 2+ phosphors were synthesized with the high-temperature solid-state reaction technique. The experimental results, summarized in the successful production of a single-phase powder with fine microstructure of spherical particles with smooth surface, suggest that Ba 2+ -doping favors the stabilization of a 0 -Sr 2 SiO 4 . Rietveld refinement of X-ray diffractograms suggests that Ba 2+ and Eu 2+ ions occupy the sites of Sr 2+ in the lattice of a 0 -Sr 2 SiO 4 . The produced phosphors show two intense emission bands at green and yellow regions of spectrum, originated from Eu 2+ ions accommodated at two different sites in the host crystal, whose peaks depend on the concentrations of Ba 2+ and Eu 2+ . Intense and broad excitation spectra extend from ultraviolet to the blue region.
