title: Dy3+-, Sm3+-, Ce3+- and Tb3+-activated optical properties of microcrystalline BaMgP2O7phosphors.
abstract: Photoluminescence (PL) and thermoluminescence (TL) properties of rare earth (RE) ion (RE = Dy3+, Sm3+, Ce3+, Tb3+) activated microcrystalline BaMgP2O7phosphors are presented in this work. Non-doped and doped samples of BaMgP2O7were prepared using a solid state diffusion method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), PL and TL. The XRD measurement confirmed the phase purity of the BaMgP2O7host matrix. The average particle size was found through SEM measurement to be around 2 μm. All activators using the PL technique displayed characteristic excitation and emission spectra that corresponded to their typical f → f and f → d transitions respectively. Thermoluminescence measurements showed that BaMgP2O7:RE (RE = Dy3+, Sm3+, Tb3+, Ce3+) and co-doped BaMgP2O7:Ce3+,Tb3+phosphors have also TL behaviour.
