Luminescence properties of novel Sm3+, Dy3+ doped LaMoBO6 phosphors

Luminescence properties and crystallographic sites for Eu3+ ions in fluorthalenite Y3Si3O10F

“…There have been extensive studies on in oxide-based phosphors such as phosphates [1][2][3], borates [4][5][6], and silicates [7][8][9][10] doped with rare earth ions. In particular, the silicate-based phosphors have recently attracted much attention because of its excellent thermal and chemical stability, lower cost, and high luminescent efficiency.…”

“…Thus the Y 3 Si 3 O 10 F silicate crystallizes in the monoclinic thalenite-type structure with space group P2 1 /n, a = 730.38(5), b = 1112.47(8), c = 1037.14(7) pm, and Z = 4 under hydrothermal conditions. The Y 3 Si 3 O 10 F lattice consists of triangular [Y 3 F] 8+ cations and catena-trisilicate anions, [Si 3 O 10 ] 8À , which contain three [SiO4 ] tetrahedral linked to a chain fragment via common corners. The Y 3+ cations are coordinated by seven oxygen ions and one fluorine ion for the Y1 site, while by six oxygen ions and one fluorine ion for the Y2 and Y3 sites.…”

Photoluminescence and time-resolved luminescence spectroscopy of novel NaBa4(BO3)3:Tb3+ phosphor

“…Recently, high quality phosphors have attracted more attention due to their practical application in the fields of display, X-ray screens, fluorescent lamps, solid state lighting, and so on [1][2][3][4][5][6][7][8]. Rare earth ions have been playing an important role in the phosphor materials due to their abundant emission colors based on their 4f-4f or 5d-4f transitions [9].…”

Photoluminescent properties of Tb3+ doped GdSrAl3O7 nanophosphor using solution combustions synthesis

“…The 4f emission spectra of RE 3+ exhibits narrow lines with high color purity as 4f electrons are well shielded by outer 5s and 5p electrons. [8][9][10] As a kind of melitite structure, lanthanide pervoskite ABC 3 O 7 (A=Ca, Sr, Ba; B=Y, La, Gd and C=Al, Ga) doped with RE 3+ ions show efficient luminescence in the visible range which make them essential to advanced display perspectives. [11][12][13][14][15][16][17][18][19][20] These compounds crystallize in tetragonal sheet-like arrangement belonging to the space group P-42 1 m. The crystal structure consists of CO 4 5− tetrahedral layers in the ab plane, perpendicular to c-axis.…”
