The recently discovered Sr[Li2Al2O2N2]:Eu2+ red phosphor, candidate for the next generation of eco‐efficient white light‐emitting diodes, exhibits excellent emission spectral position and exceptionally small linewidth. It belongs to the UCr4C4‐structure family of phosphors containing many potential candidates for commercial phosphors, whose small linewidth, tentatively ascribed to the high‐symmetry cuboid environment of the doping site, has drawn the attention of researchers in the last five…

Role of the Rigid Host Structure in Narrow-Band Green Emission of Eu2+ in Rb2Na2(Li3SiO4)4: Insights into Electron-Phonon Coupling.

Eu2+-activated alkali-lithosilicate phosphors exhibit narrow-band emissions that are attractive to high color-rendition and wide color-gamut displays. The microscopic mechanism behind the small

Suppression of Eu2+ Luminescence Loss

Owing to the intriguing luminescence properties, Eu2+ is one of the most desirable activators for next‐generation lighting devices. Yet the application of Eu2+‐doped phosphors is limited because of



First-principles studies of Ce-doped RE2M2O7 (RE = Y, La; M = Ti, Zr, Hf): A class of nonscintillators

Lanthanum and yttrium compounds with composition RE2 M2 O7 (RE = Y, La; M = Ti, Zr, Hf) have high density and high Z and can be doped with Ce onto the La and Y sites. This makes these compounds good

Beyond the one-dimensional configuration coordinate model of photoluminescence

The one-dimensional configuration coordinate model (1D-CCM) is widely used for the analysis of photoluminescence in molecules and doped solids, and relies on a linear combination of the equilibrium

New Insights in 4f(12)5d(1) Excited States of Tm(2+) through Excited State Excitation Spectroscopy.

This work demonstrates that ESE is a powerful spectroscopic tool, giving access to information which cannot be obtained through regular one-photon spectroscopy, as well as probing the equilibrium distance offset between different 4f(n-1)5d(1) excited states.

Luminescence Quenching via Deep Defect States: A Recombination Pathway via Oxygen Vacancies in Ce-Doped YAG

Luminescence quenching via non-radiative recombination channels limits the efficiency of optical materials such as phosphors and scintillators and therefore has implications for conversion efficiency
