Multicolor up conversion emission and color tunability in Yb3+/Tm3+/Ho3+ triply doped heavy metal oxide glasses
(Elsevier B.V., 2011-10-01)
Multicolor and white light emissions have been achieved in Yb3+, Tm3+ and Ho3+ triply doped heavy metal oxide glasses upon laser excitation at 980 nm. The red (660 nm), green (547 nm) and blue (478 nm) up conversion emissions ...

Tuning multicolor emission in AgNCs/Tm3+/Mn2+-doped fluorophosphate glasses
(2020-05-01)
Herein we report the synthesis of highly-doped silver nanocluster in fluorophosphate glasses through the melting-quenching method in order to achieve sensitization with Tm3+ and Mn2+ ions. Blue and red emission belonging ...
Infrared cascade and cooperative multicolor upconversion emissions in Y8V2O17:Eu:Yb nanophosphors
(Optical Society of America - OSAWashington, DC, 2013-02)
This work reports on the efficient cooperative upconversion and infrared cascade downconversion emissions in a novel Y8V2O17:Eu:Yb nanophosphor. The excitation with UV light produces emission in the 950- 1000 nm region, ...
White light and multicolor emission tuning in Ag nanocluster doped fluorophosphate glasses
(2017-01-01)
The emission properties of Ag nanoclusters (Ag NCs) dispersed in a transparent fluorophosphate glass host have been studied. The as-prepared glass shows that the Ag NCs emit a broad white emission band almost covering the ...
Precisely tailored shell thickness and Ln3+ content to produce multicolor emission from Nd3+-sensitized Gd3+-based core/shell/shell UCNPs through bi-directional energy transfer
(2019-01-01)
Lanthanide (Ln3+)-doped upconversion nanoparticles (UCNPs) have been paid great attention as multiplexing agents due to their numerous uses in biological and clinical applications such as bioimaging and magnetic resonance ...
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 ...
