Micro-environment of the Eu interstitial in -SiAlON:Eu green phosphor
Julien Bouquiaux, Samuel Poncé, Yongchao Jia +2
The precise atomic-scale structure around Eu activators in the -SiAlON:Eu commercial green phosphor remains elusive. We use the first-princ…
A First-Principles Explanation of the Luminescent Line Shape of SrLiAlN:Eu Phosphor for Light-Emitting Diode Applications
Julien Bouquiaux, Samuel Poncé, Yongchao Jia +3
White light-emitting diodes are gaining popularity and are set to become the most common light source in the U.S. by 2025. However, their performance is still limited by the lack o…
Design rule for the emission linewidth of Eu-activated phosphors
Yongchao Jia, Samuel Poncé, Anna Miglio +2
We study from first principles the emission linewidth of Eu-doped LED phosphors. Based on the one-dimensional configuration coordinate model, an analysis of first principles…
Importance of long-range channel Sr displacements for the narrow emission in Sr[LiAlON]:Eu phosphor
Julien Bouquiaux, Samuel Poncé, Yongchao Jia +3
The recently discovered Sr[LiAlON]:Eu red phosphor, candidate for the next generation of eco-efficient white light-emitting diodes, exhibits excellent emissi…
Beyond the one-dimensional configuration coordinate model of photoluminescence
Yongchao Jia, Samuel Poncé, Anna Miglio +2
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 o…
Ab initio Study of Luminescence in Ce-doped LuSiO: The Role of Oxygen Vacancies on Emission Color and Thermal Quenching Behavior
Yongchao Jia, Anna Miglio, Masayoshi Mikami +1
We study from first principles the luminescence of LuSiO:Ce (LSO:Ce), a scintillator widely used in medical imaging applications, and establish the crucial role of o…
