Intrinsic chromatic switching of visible luminescence in Yb3+,Er3+:CsCdBr3.

چکیده
Bistability is reported in sensitized Er3+ luminescence driven by an Yb3+ transition that previously revealed an Yb3+ luminescent instability. To our knowledge this is the first report of bistable energy transfer between different rare-earth ions.

Bistable emission of a black-body radiator
Bistability is common in nonlinear dynamical systems, but there have been no reports of intrinsic instabilities in black-body emission of optically excited media. Intrinsically bistable photo-luminescence has been reported however in Yb-doped heavy metal halide crystals at cryogenic temperatures and also in room temperature experiments in rare-earth-doped laser glass and transition metal laser ...
متن کاملControlled Synthesis of Monodisperse Hexagonal NaYF₄:Yb/Er Nanocrystals with Ultrasmall Size and Enhanced Upconversion Luminescence.
The ability to synthesize upconversion nanocrystals (UCNCs) with tailored upconversion luminescence and controlled size is of great importance for biophotonic applications. However, until now, limited success has been met to prepare bright, ultrasmall, and monodispersed β-NaYF₄:Yb3+/Er3+ UCNCs. In this work, we report on a synthetic method to produce monodisperse hexagonal NaYF₄:Yb3+/Er3+ nanoc...
متن کاملControlled synthesis, formation mechanism, and great enhancement of red upconversion luminescence of NaYF4:Yb3+, Er3+ nanocrystals/submicroplates at low doping level.
Strong red upconversion luminescence of rare-earth ions doped in nanocrystals is desirable for the biological/biomedical applications. In this paper, we describe the great enhancement of red upconversion emission (4F9/2 --> I15/2 transition of Er3+ ion) in NaYF4:Yb3+, Er3+ nanocrystals at low doping level, which is ascribed to the effectiveness of the multiphonon relaxation process due to the e...
متن کاملDistance Dependence of Gold-Enhanced Upconversion luminescence in Au/SiO2/Y2O3:Yb3+, Er3+ Nanoparticles
We report a localized surface plasmon enhanced upconversion luminescence in Au/SiO2/Y2O3:Yb3+,Er3+ nanoparticles when excited at 980 nm. By adjusting the silica spacer's thickness, a maximum 9.59-fold enhancement of the green emission was obtained. Effect of the spacer distance on the Au-Y2O3:Yb3+, Er3+ green upconversion mechanism was numerically simulated and experimentally demonstrated. In t...
متن کاملThe Upconversion Luminescence of Er3+/Yb3+/Nd3+ Triply-Doped β-NaYF4 Nanocrystals under 808-nm Excitation
In this paper, Nd3+-Yb3+-Er3+-doped β-NaYF₄ nanocrystals with different Nd3+ concentrations are synthesized, and the luminescence properties of the upconversion nanoparticles (UCNPs) have been studied under 808-nm excitation for sensitive biological applications. The upconversion luminescence spectra of NaYF₄ nanoparticles with different dopants under 808-nm excitation proves that the Nd3+ ion ...
