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…
Predominance of non-adiabatic effects in zero-point renormalization of the electronic band gap
Anna Miglio, Véronique Brousseau-Couture, Emile Godbout +6
Electronic and optical properties of materials are affected by atomic motion through the electron-phonon interaction: not only band gaps change with temperature, but even at absolu…
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…
First-principles Study of the Luminescence of Eu2+-doped Phosphors
Yongchao Jia, Anna Miglio, Samuel Poncé +2
The luminescence of fifteen representative Eu-doped phosphors used for white-LED and scintillation applications is studied through a Constrained Density Functional Theory. T…
