Abstract

The luminescence properties of Ce

activated BaCa

(BO

)

phosphors were investigated by vacuum-ultraviolet (VUV) and ultraviolet(UV) spectra. The phase purity was characterized by the powder x-ray diffraction (XRD). The results demonstrate that the band near 140～190 nm range in the VUV excitation spectra is ascribed to the host-related absorption. The lowest 5d state of Ce

in BaCa

(BO

)

is located at 360 nm

and two emission bands from Ce

(

=5/2

7/2) were found at about 393

424 nm. The emission bands of Tb

-doped BaCa

(BO

)

consists of four components

which correspond to the

(

6) transitions with the dominant

transition at 543 nm. The energy-transfer between Ce

and Tb

occurs in Ce

co-activated BaCa

(BO

)

phosphors.
