Analysis of Er3+ incorporation in SnO2 by optical investigation
(Sociedade Brasileira de Física, 2006-06-01)
Er3+ emission in the wide bandgap matrix SnO2 is observed either through a direct Er ion excitation process as well as by an indirect process, through energy transfer in samples codoped with Yb3+ ions. Electron-hole ...

Photoluminescence and Structural Analysis of Er3+/Yb3+/Tm3+ Triply Doped Gd2O3
(Brazilian Chemical Soc, 2017-01-01)
Spectroscopic and structural properties of Er3+:Yb3+:Tm3+ triply doped Gd2O3 nanocrystals were investigated. The effect of heat treatment at 800, 900, 1000 and 1100 degrees C for 4h, on the luminescence and the energy ...
Spectroscopic properties of Er3+ in oxysulfide glasses
(Elsevier B.V., 2002-10-07)
Er3+ -containing gallium-lanthanum oxysulfide glasses have been prepared from Ga2O3 and La2S3 in a sulfur/argon reactive atmosphere. The samples have been characterized by absorption and emission spectroscopy and IR emission ...

1.5 mu m emission and infrared-to-visible frequency upconversion in Er+3/Yb+3-doped phosphoniobate glasses
(Elsevier B.V., 2006-09-15)
Sodium phosphoniobate glasses with the composition (mol%) 75NaPO(3)-25Nb(2)O(5) and containing 2 mol% Yb3+ and x mol% Er3+ (0.01 <= x <= 2) were prepared using the conventional melting/casting process. Er3+ emission at 1.5 ...

Expanding broadband emission in the near-IR via energy transfer between Er3+ -Tm3 co-doped tellurite-glasses
(Elsevier BVAmsterdam, 2014-01)
Processes of energy transfer in Er3+ -Tm3 co-doped tellurite glasses has permitted to obtain an expanding broadband emission in the near-infrared region covering the bands S, C+L and U of the optical telecommunications and ...
The influence of the complexing agent on the luminescence of multicolor-emitting Y2O3:Eu3+,Er3+,Yb3+ phosphors obtained by the Pechini's method
(2021-01-01)
In this study, it is reported the enhancement of the downshifting and the upconversion emission of Y2O3:Eu3+,Er3+,Yb3+ phosphor drove by sorbitol instead of the classic ethylene glycol used as polymerizing agent in the ...
Study of the influence of Er/Ln co-doping in La2O3 thin films on their up-conversion properties (where Ln ¼ Ho or Nd)
(Elsevier, 2020)
In this study we report significant enhancement of up-conversion emissions of La2O3:Er thin films when they are co-doped with Er/Ln (where Ln = Nd or Ho). The proposed mechanisms by which the Ln ions contribute to these ...
