Hydrothermal synthesis and luminescence properties of monodisperse BaWO4:Eu3+ submicrospheres

Development of SrWO4:Ho3+/Yb3+ green phosphor for optical thermometry application

“…The strong absorption bands at 411 and 816 cm À1 Table 1 Unit cell parameters of different concentrations of Ho 3+ doped and 10 mol% Yb 3+ co-doped SrWO 4 phosphors correspond to the characteristic W-O and O-W-O stretching vibrations of the tetragonal SrWO 4 crystal. 18,19 The characteristic vibrational band of SrWO 4 does not show any wavenumber shift and does not introduce any extra vibrational band with a change in Ho 3+ ion concentration. The above two observations reveal that the addition of Ho 3+ ions occurred as a dopant and could not alter the crystal structure of the material.…”

Energy transfer and luminescent properties in Tb3+ and Eu3+ co-doped CaMoO4/SrMoO4 thin films

“…In the recent years, rare earth ions-doped molybdates have been widely studied due to their excellent chemical, optical, and thermal properties. Rare earth ions doped luminescent materials have abundant emission spectra, because of their 4f orbits with rich energy levels [1][2][3][4][5][6][7][8]. Eu 3+ and Tb 3+ are red and green light activator ions, which have been well investigated in many luminescent materials [9][10][11][12][13][14].…”

Luminescence Properties of Phosphate Phosphor: Barium Tungstate Doped with Dy

“…The BaWO 4 luminescent materials doped with Tb 3+ or Eu 3+ have been reported that they can be synthesized by a simple hydrothermal route, and show potential applications in the field of phosphor-converted white LEDs [10] [11]. Alkaline-earth metal tungstate AWO 4 ) was used to study as phosphor self-excited under UV excitation, exhibiting blue or green light [12].…”
