Efficient white light emission by upconversion in Yb(3+)-, Er(3+)- and Tm(3+)-doped Y2BaZnO5.
We report efficient white upconversion luminescence in Yb(3+)-, Er(3+)- and Tm(3+)-doped monophasic and biphasic Y(2)BaZnO(5) phosphors under 977 nm near-infrared excitation and at low excitation power densities (down to ∼25 mW mm(-2)).
متن کاملSynthesis of brightly PEGylated luminescent magnetic upconversion nanophosphors for deep tissue and dual MRI imaging.
A method is developed to fabricate monodispersed biocompatible Yb/Er or Yb/Tm doped β-NaGdF4 upconversion phosphors using polyelectrolytes to prevent irreversible particle aggregation during conversion of the precursor, Gd2 O(CO3 )2.H2 O:Yb/Er or Yb/Tm, to β-NaGdF4 :Yb/Er or Yb/Tm. The polyelectrolyte on the outer surface of nanophosphors also provided an amine tag for PEGylation. This method i...
متن کاملDual energy converting nano-phosphors: upconversion luminescence and X-ray excited scintillation from a single composition of lanthanide-doped yttrium oxide.
We report an upconverting nanomaterial composition, [Y(2)O(3); Yb (2%), Er (1%)], that converts both X-ray and high-fluence NIR irradiation to visible light. This composition is compared to a higher Yb(3+) doped composition, [Y(2)O(3); Yb (10%), Er (1%)], that displays diminished visible X-ray scintillation, but shows enhanced red wavelength centered upconversion emission. These nanocrystals ha...
متن کاملBlue upconversion emission of Tm–Yb in ZrO2 nanocrystals: Role of Yb ions
The effect of Yb ions on the blue upconversion (UPC) emission of Yb–Tm co-doped ZrO2 nanocrystals is reported. The blue (490 nm) UPC emission is due to G4– H6 transition of Tm 3+ and the pump power dependence of this UPC emission band are cubic indicating that three excitation photons are involved in the UPC process. An additional UPC emission band at 505 nm is observed when the Yb concentratio...
متن کاملFrequency upconversion emissions in layered lead–germanate–tellurite glasses for three-color display
This letter is aiming to develop a full-color glass for the three-dimensional and three-color display. The Yb/Tm/Er codoped lead–germanate–tellurite bulk glass has been fabricated and the upconversion emissions have been investigated. The reduced blue and green emission intensity suggests that it is difficult to achieve three-color display in the multiple-rare-earth ions doped glass. Then a two...
