TL;DR: Investigation of the overheating caused by 980 nm excitation laser light in UC bioimaging and imaging and spectroscopy analysis of UC photoluminescence demonstrated that a 915 nm laser can serve as a new promising excitation light for UC animal imaging.
Journal ArticleDOI
Upconversion Emission Enhancement in Yb3+/Er3+-Codoped Y2O3 Nanocrystals by Tridoping with Li+ Ions
TL;DR: In this article, tridoping with Li+ ions enhances the visible green and red upconversion (UC) emissions in Er3+/Yb3+-codoped Y2O3 nanocrystals by up to half of the bulk counterpart.
Journal ArticleDOI
Upconversion emission tuning from green to red in Yb3+/Ho3+-codoped NaYF4 nanocrystals by tridoping with Ce3+ ions
TL;DR: Theoretical investigations based on steady-state equations demonstrate the proposed UC mechanisms and explain well the observed linear increase of the UC red-to-green intensity ratio with the increment of Ce(3+) ion concentrations.
Journal ArticleDOI
Upconversion mechanism for two-color emission in rare-earth-ion-doped Zr O 2 nanocrystals
TL;DR: In this article, two-color upconversion (UC) emissions with anomalous power dependence were observed in spectrally tailored rare-earth ion-doped nanocrystals, yielding quadratic and linear laser power dependences, respectively.
Journal ArticleDOI
Bright white upconversion luminescence in rare-earth-ion-doped Y2O3 nanocrystals
TL;DR: In this paper, the authors proposed a room temperature bright white upconversion (UC) luminescence in Yb3+−Tm3+Er3+ ions doped with Y2O3 nanocrystals was obtained under single-wavelength diode laser excitation of 976nm.
