Abstract
The single-phase CaAl2O4(CA) : Eu2+ powder phosphors showing 440 nm blue em ission were prepared by two-step firing synthesis. It is expected that CA:E u2+ phosphor can be applied to plasma display panels (PDPs), because it is more resistant to luminance degradation by heating process in comparison to BaMgAl10O17(BAM) : Eu2+. However, the initial PL luminance of CA : Eu2+ ex cited by 147 nm light remains 50% of that of BAM :Eu2+. (C) 2000 Elsevier S cience B.V. All rights reserved.
