PDP, BaAl12O19: Mn2+ Phosphors, Coating, Thermal Degradation, Heterogeneous NucleationBaAl12O19: Mn2+ phosphors were coated with a uniform compact MgF2 film according to the heterogeneous nucleation method. By precisely controlling the parameters of coating process, XRD and SEM analysis confirm ...
The zero-field splittings D and E for Mn2+ in MgF2 crystal have been calculated from the superposition model and the spin-orbit mechanism. The results show reasonable agreement with the experimental values. The disparity in magnitude between calculation and experiment in the case of using spin-...
