Green-Emitting Gd3Ga5O12: Tb3+ Nanoparticles Phosphor: Synthesis, Structure, and Luminescence
Nano- and microceramics of Gd3Ga5O12 garnet doped with 1 mol % Tb3+ ions were synthesized via co-precipitation and high-temperature solid-state reaction methods. X-ray diffraction measurements confirmed the formation of the garnet structure with Ia3d space group in all investigated samples. Atomic force microscopy surface images and grain-size distribution diagrams of Gd3Ga5O12: 1 mol % Tb3+ na...

New Ce3+-activated thiosilicate phosphor for LED lighting-synthesis, luminescence studies, and applications.
A new Ce(3+)-activated thiosilicate phosphor, BaLa2Si2S8:Ce(3+), was synthesized by using solid-state methods in a fused silica ampule and found to crystallize in the structure type of La2PbSi2S8. The crystal structure has been characterized by synchrotron X-ray diffraction and refined with Rietveld methods. This novel cyan-emitting phosphor can be excited over a broad range from UV to blue lig...

15 صفحه اولSynthesis and luminescence properties of a blue-emitting Sr3.5Y6.5O2(PO4)1.5SiO4(4.5) :Eu2+ phosphor.
A novel blue-emitting Sr3.5Y6.5O2(PO4)1.5SiO4(4.5) :Eu2+ phosphor was synthesized via a solid-state reaction. Powder X-ray diffraction (XRD) analysis demonstrated that the Sr3.5Y6.5O2(PO4)1.5(SiO4)4.5 host had a hexagonal crystal structure in the space group P6(3) /m and unit cell parameters a = 9.418 Å, c = 6.900 Å. The as-prepared phosphor showed a blue emission and all the main emission peak...
