Abstract

In this work

Y(PV)O

:Eu

phosphors were coated with Y(OH)

by the coprecipitation process. The surface morphology and the crystal structure were characterized by SEM and XRD

respectively. The results indicated that the surface of Y(PV)O

:Eu

phosphors are evenly coated by Y(OH)

and the crystal structure of the coated Y(PV)O

:Eu

phosphors remains the same with the uncoated samples

i.e.

after surface treatment

the luminance centre of Eu

does not shift

the emission is still at about 620 nm. The color coordinates of Y(PV)O

:Eu

are

=0.660

=0.340

so it can meet the requirement of PDP. The emitting spectra of Y(PV)O

:Eu

phosphor particles coated with Y(OH)

and without coating were investigated under 308 nm excitation. The results demonstrated that the initial luminance of coated Y(PV)O

:Eu

phosphors is higher than the uncoated samples. This method is simple

convenient and economical as compared with other methods.
