Synthesis, luminescence and effect of heat treatment on the properties of Dy3+-doped YVO4 phosphor

New Single-Phase, White-Light-Emitting Phosphors Based on δ-Gd2Si2O7 for Solid-State Lighting

“…27 The fact that this transition was clearly observed in our spectra indicates that Dy 29,30 and has been assigned to the influence of other factors like the electronegativity of the next-nearest neighbors, which influences the covalency of the Dy-O bond. 31 The Y/B ratio observed for the δ-Gd 2 Si 2 O 7 :Dy 3+ phosphors analyzed in this study resulted very adequate for the generation of white light.…”

Multiwavelength excited white-emitting phosphor Dy3+-activated Ba3Bi(PO4)3

“…Therefore, the color tone of Dy 3+ -doped phosphors can be modified by changing the relative intensity of the yellow light through crystal field engineering. At present, There are many hosts that can be activated by Dy 3+ ions, such as borates [2][3][4], phosphates [5][6][7][8], aluminates [9,10], silicates [11][12][13], vanadates [14][15][16], and molybdates [1]. Among these phosphors investigated, phosphates are good candidates due to their low synthetic temperatures, stabilities, and low costs.…”

Preparation and characterization of nanosized (Y,Bi)VO4:Eu3+ and Y(V,P)O4:Eu3+ red phosphors

“…Nanosized semiconductor and metal oxide luminescence materials are of great interest because of wide applications for display, energy, environmental, and biological technologies [1][2][3][4][5][6][7][8][9][10][11]. Owing to the special structural, electronic, and optical properties, nanocrystalline materials may offer new possibilities for advanced phosphor applications, such as new types of flat panel displays and lightings [4][5][6].…”

“…Solution methods have shown to be very powerful technique to prepare well-dispersed nanoparticles with controlled size, shape, and surface state. There are various low-cost liquid-phase methods preparing nanoparticles such as sol-gel, spray, reversed micelle, redox reaction, and ligand-exchanging reaction methods [7][8][9][10][11]. Particle size, morphology, agglomeration, or surface defects have a great impact on the luminescence efficiency [11].…”

“…Higher fluorescence intensities were achieved for PDP applications by replacement of the VO 4 3À ion with isomorphic PO 4 3À ion in the YVO 4 :Eu 3+ phosphor lattices [20][21][22][23]. Moreover, recent investigations show that nanosized YVO 4 :Eu 3+ luminescent materials have a significant promise in high-definition flat display panels [4][5][6][9][10][11]. Particular interest is focused on the effects of compositions, morphologies, and particle dimensions on the optical properties.…”
