Energy transfer from Bi3+ to Eu3+ triggers exceptional long-wavelength excitation band in ZnWO4:Bi3+, Eu3+ phosphors

Surface Plasmon Resonance Enhanced Spontaneous Upconversion and Stimulated Emissions in Glass Ceramics Containing Ba2LaF7 Nanocrystals

“…The lifetime decreases after the first increase, and the variation tendency agrees well with the change of UC luminescence intensities of green emission. The lifetime result is an evidence of an accelerating energy transfer from Yb 3+ to Er 3+ with increasing Ag NPs content [24,25], which indicates that some energy transfer from fluorescent Ag NPs to Er 3+ cannot be totally ignored. Interestingly, microcavities can be realized by randomly embedding Ba 2 LaF 7 :Yb 3+ , Er 3+ nanocrystals inside the glass and random lasing action can be achieved in the glass ceramic.…”

A novel single-phase white phosphor NaBaBO 3 :Dy 3+ ,K + for near-UV white light-emitting diodes

“…Fig.10 show the decay curves for the F 9/2 → 6 H 15/2 transition of the Dy 3+ ion of NBB:xDy 3+ (x = 0.05, 0.07) and NBB:xDy 3+ ,xK + (x = 0.05, 0.07) samples. As shown in the inset of Fig.10, the decay curves can be well fitted to a double-exponential decay model by the following equation [42]:…”

Effect of annealing on the structural, optical and emissive properties of SrWO4:Ln3+ (Dy3+, Eu3+ and Sm3+) nanoparticles

“…They have been studied widely due to their several applications in catalysts, scintillation detector, w-LEDs, photoluminescent devices, optics fiber, solar cell, fluorescent lamps and more [1][2][3][4][5][6][7][8]. Improvement of the luminescence properties of scheelite based phosphors has become a primary focus in the luminescent materials science.…”
