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…
Fröhlich polaron effective mass and localization length in cubic materials: degenerate and anisotropic electronic bands
Bogdan Guster, Pedro Melo, Bradley A. A. Martin +7
Polarons, that is, charge carriers correlated with lattice deformations, are ubiquitous quasiparticles in semiconductors, and play an important role in electrical conductivity. To…
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…
