On BaMgAl10O17:Eu2+ phosphor degradation mechanism: thermal treatment effects
Gregory Bizarri,Bernard Moine +1 more
TL;DR: In this paper, a model of the degradation process of PPDP phosphor during panel fabrication and during panel life is presented. But the degradation mechanism is not yet fully clarified, and the degradation is due to three different mechanisms: the adsorption of an oxygen atom of the atmosphere into an oxygen vacancy of the surface phosphor, the diffusion of divalent europium ions along the conduction layer of BAM and the transfer of one electron from dopant ions to adsorbed oxygen ions when the divalentEuropium ion are close to adsored oxygen ions
