Infrared to visible up-conversion emission in Er3+/Yb 3+ codoped fluoro-phosphate glass-ceramics
(2013-03-01)
Erbium Er3+ and ytterbium Yb3+ codoped fluoro-phosphate glasses belonging to the system NaPO3-YF 3-BaF2-CaF2 have been prepared by the classical melt-quenching technique. Glasses containing up to 10 wt% of erbium and ...

Preliminary evaluation of the up-conversion emission of Y2O3:Er-Yb thin films prepared by a solid state photochemical deposition method
(Elsevier, 2018)
Y2O3 thin films doped with different concentrations of erbium ions and co-doped with 10 mol% of ytterbium were synthesized by a solid state photochemical deposition method followed by a subsequent calcination process. The ...
A portable luminescent thermometer based on green up-conversion emission of Er3+/Yb3+ co-doped tellurite glass
(2017-01-31)
The determination of temperature is essential in many applications in the biomedical, technological, and industrial fields. Optical thermometry appears to be an excellent alternative for conventional electric temperature ...
Green-to-red light tuning by up-conversion emission via energy transfer in Er3+-Tm3+-codoped germanium-tellurite glasses
(Elsevier BVAmsterdam, 2014-06)
The luminescence properties through up-conversion emission process of Er3+-Tm3+-codoped germanium- tellurite glasses was carefully investigated by using UV-visible-near-infrared absorption spectroscopy, emission spectroscopy ...

Giant enhancement of phonon-assisted one-photon excited frequency upconversion in a Nd3+-doped tellurite glass
(2013-02-07)
Changing the sample's temperature from 200 K to 535 K, we observed 670-fold enhancement of a phonon-assisted upconversion emission at ≈754 nm obtained from a Nd3+-doped tellurite glass excited by 5 ns laser pulses at 805 ...
