Abstract

The plasma display panels PDPs are regarded as a medium of large-format panel display. The performance and lifetime of PDPs are strongly related to the nature of phosphors used in it. The working of PDPs is realized by a conversion of vacuum ultraviolet VUV light to visible light. VUV light has higher energy than that of the ultraviolet (UV) light used as the excitation source of conventional lamp phosphors

therefore

the surface morphology of PDP phosphors suffering from VUV radiation is damaged

and the luminescent performance is decreased with PDPs working time

thus shortening the life of PDPs. This indicates that PDP phosphors should not only have high luminescent efficiency

but also are highly resistant to VUV radiation. Obviously

it is essential to choose an appropriate coating material to resist the VUV radiation.In this work

BaAl

:Mn

powders were prepared by the conventional solid-reaction method. MgF

was coated at the surface of BaAl

:Mn

powders by the emulsion method. Some factors

such as reagent concentration and reaction procedure

were investigated

the optimal coating conditions and technique were obtained. The structure analysis of surface-modified (BaAl

:)Mn

powders was performed by XRD

TEM

IR measurements. The phosphor screen was prepared also for the aging measurement.The results indicated that MgF

was successfully coated at the surface of BaAl

:Mn

. The luminescent intensity of surface-modified BaAl

:Mn

decreased only 1.6% at the starting. After aging for 8 h

the luminescence decay of surface-modified samples was significantly less than that of non-modified samples.
