摘要：

The oxygen effect on BaAl2S4:Eu phosphor microstructure has been revealed by Transmission Electron Microscopy (TEM) analyses. Oxidation driven aluminum segregation caused the inhomogeneous phosphor film microstructure and stacking faults in the phosphor. Stable and high efficient BaAl2S4:Eu phosphor in TDEL deices have been achieved by optimizing oxidation during phosphor process which reduces the defects level and eliminate the segregation of aluminum at the lower interface between phosphor and lower dielectric.
