The photoluminescence properties of rare-earth (lanthanide) compounds have been
fascinating researchers for decades. 1-14 An attractive feature of luminescent lanthanide …

Luminescent materials with the quantum efficiency (QE) higher than unity could be playing a
significant role in the progress of lighting industry and certain electronic display systems …

We present experimental evidence for cooperative energy transfer from Tb 3+ to two Yb 3+
ions and a determination of the energy-transfer rate. Energy transfer from Tb 3+ to Yb 3+ …

Transfer of energy occurs endlessly in our universe by means of radiation. Compared to
energy transfer (ET) in free space, in solid state materials the transfer of energy occurs in a …

An efficient near-infrared (NIR) quantum cutting (QC) in Gd Al 3 (BO 3) 4: RE 3+, Yb 3+(⁠
RE= Pr⁠, Tb, and Tm) phosphors has been demonstrated, which involves the conversion of …

Tb 3+–Yb 3+ codoped transparent oxyfluoride glass ceramics containing Ca F 2
nanocrystals were synthesized. The formation of Ca F 2 nanocrystals in the glass ceramics …

Quantum cutting downconversion (DC) involving the emission of two near-infrared (NIR)
photons for each ultraviolet (UV) photon absorbed is realized in the Ce 3+/Yb 3+ codoped …

An efficient near-infrared (NIR) quantum-cutting (QC), involving the emission of two low-
energy NIR photons from an absorbed visible photon via a cooperative downconversion …

Abstract Tb 3+ and Yb 3+ co-activated luminescent material that can cut one photon of
around 483 nm into two NIR photons of around 1000 nm could be used as a …

Yb3+-doped oxyfluoride glass ceramics were fabricated by melt-quenching and subsequent
heating. X-ray diffraction and high-resolution transmission electron microscopy analyses …
