Synthesis and characterization of novel Na15(SO4)5F4Cl:Ce3+halosulfate phosphors

Abstract: A series of Na (SO ) F Cl phosphors doped with Ce ions was prepared using the wet chemical method. X-Ray diffraction studies were used to determine their phase formation and purity. Fourier transform infrared spectroscopy effectively identified the chemical bonds present in the molecule. The photoluminescence properties of the as-prepared phosphors were investigated and the Ce ions in these hosts were found to give broadband emission in the UV range. For the thermoluminescence study, phosphors were irradiated … Show more

“…The glow curve shows two peaks, a prominent peak at 148°C and another at 255°C compared with the TL glow curve for γ‐ray‐exposed samples that showed single peak at 160°C. Heavy carbon ions lost their whole energy after penetrating the phosphor, this action perturbed the normal lattice site and therefore altered the trapping mechanism and resulted in the generation of new trap centres that caused the peak at 255°C. The present phosphor showed a maximum TL intensity at 0.7 mol% of Dy when exposed to the C 5+ ion beam fluence 1 × 10 11 ions/cm 2 .…”

“…Na 2 ZnP 2 O 7 has been prepared as a host material for activator ions such as for a green phosphor (Na 2 ZnP 2 O 7 :Cr 3+ ), [ 20 ] reddish‐orange phosphors (Na 2 ZnP 2 O 7 :Eu 3+ ), [ 21 ] red phosphors (Na 2 ZnP 2 O 7 :Mn 2+ ) [ 22 ] and a near UV‐violet phosphor (Na 2 ZnP 2 O 7 :Ce 3+ ). [ 23 ] But, to the best of our knowledge, there has been no report in the literature dealing with the luminescence properties of a Tb 3+ ion‐doped Na 2 ZnP 2 O 7 phosphor.…”
