Journal ArticleDOI
K_2SiF_6:Mn^4+ as a red phosphor for displays and warm-white LEDs: a review of properties and perspectives
TL;DR: In this paper, a review summarizing research since 2008 on K2SiF6:Mn4+ as the first and most discussed fluoride phosphor is presented, showing the evolution from etching Si wafers to solution synthesis resulting in consistent luminescent and thermal properties.
Journal ArticleDOI
Hybrid remote quantum dot/powder phosphor designs for display backlights.
TL;DR: General guidelines are derived to optimize both the cost and efficiency of CdSe/CdS and other (potentially cadmium-free) quantum dot systems and when reabsorption of the green and/or red emission is significant compared to the absorption strength for the blue emission of the pumping light emitting diode, the hybrid remote phosphor approach becomes beneficial.
Journal ArticleDOI
Trapping and detrapping in SrAl 2 O 4 : Eu , Dy persistent phosphors: Influence of excitation wavelength and temperature
TL;DR: In this article, the authors investigated the origin of the green and blue emission bands of a persistent luminescent phosphor and attributed this to europium ions substituting for the two different Sr sites in the monoclinic host lattice.
Journal ArticleDOI
Absolute determination of photoluminescence quantum efficiency using an integrating sphere setup.
Sven Leyre,Eduardo Coutino-Gonzalez,Jonas Joos,Jana Ryckaert,Youri Meuret,Dirk Poelman,Philippe Smet,Guy Durinck,Johan Hofkens,Geert Deconinck,Peter Hanselaer +10 more
TL;DR: An integrating sphere-based setup to obtain a quick and reliable determination of the internal quantum efficiency of strongly scattering luminescent materials is presented and it was found that both measurement procedures are valid.
Journal ArticleDOI
First-Principles Study of Antisite Defect Configurations in ZnGa2O4:Cr Persistent Phosphors
Arthur De Vos,Kurt Lejaeghere,Danny E. P. Vanpoucke,Jonas Joos,Philippe Smet,Karen Hemelsoet +5 more
TL;DR: The stability analysis reveals that the distance between both antisites dominates the overall stability picture of the material containing the Cr dopant and an antisite pair, and the findings are further rationalized using calculated densities of states and Hirshfeld-I charges.
