“…This fit value should be compared to the low frequency (long wavelength) limit of the crystal refractive index n in the visible range. The latter may be estimated from a recently measured refractive index dispersion [24] as e(1) = n 2 (l ! 1) = 3.78.…”

Three-dimensional pomponlike europium-doped sodium gadolinium tungstate NaGdWO4(OH) x :Eu3+ microarchitectures that exhibit efficient white-light photoluminescence properties have been successfully synthesized via a facile hydrothermal process in the presence of the surfactants cetyl trimethyl ammonium bromide, poly(vinyl pyrrolidone), and poly(ethylene glycol)-block-poly(propylene glycol)-block-ploy(ethylene glycol). The white light sodium gadolinium tungstate phosphor contains three emission bands: the blue-green band at 468 nm is ascribed to the ligand to metal charge transfer transition from O→W; the orange band at 590 nm and red band at 610 nm are attributed to the 5D0→7F1 and 5D0→7F2 transitions of Eu3+. The luminescence color can be tuned from blue to white to red by adjusting the doping concentration of Eu3+. Both scanning electron and transmission electron microscopy indicate that the obtained microspheres have a uniform particle size distribution. The three-dimensional sodium gadolium tungstate pompon-shaped structures were constructed layer-by-layer from a large number of two-dimensional nanoflakes with a mean diameter of ∼100 nm. The whole time-dependent process is interpreted as an example of self-assembly process. The emission spectra are dominated by a 5D0→7F2 transition of Eu3+. The optimum concentration for the white light was to keep the ratio of Eu3+ and Gd3+ at about 0.02.

“…4. In addition, the experimental data of refractive indexes are fitted based on the Sellmeier dispersion equation: 24 The constants are fitted to be S = 2.65528 and λ 0 = 129.93436 nm. Then, by using these two constants, the refractive indexes of the Er,Pr:LuYSGG crystal in the range of 320–3000 nm can be calculated, which decrease gradually with the increase of wavelength.…”
