Simultaneous enhancement of photoluminescence and afterglow luminescence through Bi3+ co-doping in the Sr3Al2O5Cl2:Eu2+ phosphor
In this work, the Sr 3 Al 2 O 5 Cl 2 :Eu 2+ and Sr 3 Al 2 O 5 Cl 2 :Eu 2+ ,Bi 3+ phosphors are synthesized by high temperature solid state reactions. Various characterization techniques, such as X-ray diffraction (XRD), Rietveld refinement, photoluminescence (PL) spectroscopy, afterglow spectroscopy...
