Abstract

Phosphors Ca

9(1-

x-y

)

Al(PO

)

were synthesized by solid-state reaction method at high temperature under a reducing atmosphere of CO

and the luminescent properties of the phosphors were investigated. The X-ray diffraction patterns (XRD) show that a pure phase of Ca

Al(PO

)

phosphor has been obtained after calcined at 1 200℃. Under 268 nm excitation

the Ca

Al(PO

)

:Ce

sample exhibits a broad emission band centered at 363 nm. The emission spectrum of Ca

Al(PO

)

:Dy

sample under 350 nm excitation shows two characteristic emissions of Dy

located at 483 nm and 574 nm

corresponding with

9/2

15/2

and

9/2

13/2

transition

respectively. According to the fluorescence spectra

the characteristic emissions of Dy

are significantly sensitized by Ce

when the Ca

Al(PO

)

samples are co-doped with Ce

and Dy

. Adjusting the concentration of Ce

and Dy

the color of the phosphors can change from yellowish-white to white. The results indicate that the optimal mole fractions of Ce

and Dy

in Ca

9(1-

x-y

)

Al(PO

)

are

=0.02 and

=0.02

and the chromaticity coordinate is (0.306

0.313).
