“…Search for new materials with improved scintillation characteristics is of big importance. Cerium-doped lutetium scandium orthoborate (Lu 1−x Sc x )BO 3 [2], gadolinium silicate Gd 9.33 (SiO 4 ) 6 O 2 (GSAP:Ce) [3], Ce, Na-codoped lutetium silicate Lu 2 SiO 5 [4] are the recent examples of new scintillation materials based on complex oxides. Ce-doped rare earth pyrosilicates (disilicates) RE 2 Si 2 O 7 are among the most promising new scintillators.…”

Broad-band near-ultraviolet (NUV)-excited and multicolor-emitting Gd2SiO5:Ce3+,Tb3+,Eu3+ phosphors were synthesized by solid-state reaction. The emission color of the phosphors can be tuned from blue (0.153, 0.091) to green (0.325, 0.495) and eventually to red (0595, 0.370) through efficient Ce3+ → (Tb3+) n → Eu3+ energy transfer. NUV light was strongly absorbed by the Ce3+ ions, and the excited energy was transferred to Tb3+ ions, which produced intense green emission peaks. Finally, the excited energy was transferred from Tb3+ to Eu3+ ions, which is attributed to red emission peaks. These multicolor tunable Gd2SiO5:Ce3+,Tb3+,Eu3+ phosphors are promising materials for applications in NUV light-emitting diodes.

“…3,4 Oxide phosphors have been developed for FED applications because of the better thermal and chemical stability and environmental friendliness compared with sulfides. 5,6 Recently, much attention has been focused on lanthanide ions for their superior luminescent properties. [7][8][9] Inorganic materials doped with lanthanide ions are particularly suitable for display applications.…”

“…Silicates with chemical and thermal stability are known as excellent host materials for cathodoluminescence phosphors, and many studies have been reported on ZnSiO 4 : Mn 2+ and Y 2 SiO 5 :Tb 3+ . 5,[14][15][16][17][18] La 9.33 (SiO 4 ) 6 O 2 belongs to the rare-earth-metal silicates with an oxyapatite structure which has been reported to be a new oxide ion conductor. 19 Hiroki Okudera et al investigated the structural parameters of La 9.33 (SiO 4 ) 6 O 2 and confirmed that the crystallographic space group was P6 3 /m.…”

One-dimensional La(9.33)(SiO(4))(6)O(2): Ln(3+) (Ln = Ce, Eu, Tb) microfibers were fabricated by a simple and cost-effective electrospinning method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), photoluminescence (PL) and low voltage cathodoluminescence (CL) as well as kinetic decay were used to characterize the resulting samples. SEM and TEM results indicated that the diameter of the microfibers annealed at 1000 °C for 3 h was 200-245 nm. The microfibers were further composed of fine and closely linked nanoparticles. La(9.33)(SiO(4))(6)O(2): Ln(3+) (Ln = Ce, Eu, Tb) phosphors showed the characteristic emission of Ce(3+) (5d → 4f), Eu(3+) ((5)D(0)→(7)F(J)) and Tb(3+) ((5)D(3,4)→(7)F(J)) under ultraviolet excitation and low-voltage electron beams (3-5 kV) excitation. An energy transfer from Ce(3+) to Tb(3+) was observed in the La(9.33)(SiO(4))(6)O(2): Ce(3+), Tb(3+) phosphor under ultraviolet excitation and low-voltage electron beam excitation. Luminescence mechanisms were proposed to explain the observed phenomena. Blue, red and green emission can be realized in La(9.33)(SiO(4))(6)O(2): Ln(3+) (Ln = Ce, Eu, Tb) microfibers by changing the doping ions. So the La(9.33)(SiO(4))(6)O(2): Ln(3+) (Ln = Ce, Eu, Tb) phosphors have potential applications in full-color field emission displays.
