Codopant ion-induced tunable upconversion emission in β-NaYF4:Yb3+/Tm3+ nanorods.

Dalton Trans. 42(5) , 1834-41, (2013)

An innovative route to tune upconversion (UC) emission in β-NaYF(4):Yb(3+)/Tm(3+) nanorods through codoping a third rare-earth ion upon continuous wave excitation near 976 nm is reported. The dependen...

Near-infrared to visible upconversion in Tm3+ and Yb3+ codoped Lu2O3 nanocrystals synthesized by hydrothermal method.

J. Nanosci. Nanotechnol. 14(6) , 4313-9, (2014)

Lutetium oxide nanocrystals codoped with Tm3+ and Yb3+ have been successfully synthesized via adjusting the pH values of the precursor solution in a hydrothermal method followed by a subsequent calcin...

Evidence of Tm impact in low-photodarkening Yb-doped fibers.

Opt. Express 21(6) , 7590-8, (2013)

In contrast to Yb/Al-doped fibers, the influence of very low Tm(2)O(3) concentrations (≥ 0.1 mol-ppm) on photodarkening (PD) is clearly detectable in Yb/P-doped fibers that are known to show little de...
